Authors: Wu Da Zhi , Zhang Zhen Ying
Published: January 2014

By using the finite element method, the settlement of soft soil subgrade with a crust layer has been investigated. To find the influence of thickness of the crust layer on the settlement, four different thicknesses, which are 0.0m, 1.5m, 3.5m and 5.5m, are selected. Besides, the settlement during the construction and post construction are also analyzed. It is found that the crust layer can reduce the settlement and uneven settlement of subgrade effectively. Besides, the settlement of the subgrade decreases with the increase of the thickness of crust layer. Moreover, with the increase of time, the uneven settlement of the pavement increases gradually. And when the time is up to a certain degree, the uneven settlement tends to be stable.

Published: January 2014

We present a nonparametric comparative efficiency analysis of urban public transport systems (UPTS) in Shanghai (2004-2012). The UPTS include urban public bus transit system (UPBTS) and urban public rail transit system (UPRTS). We apply data envelopment analysis (DEA) to assess the technical, pure technical and scale efficiencies of UPBTS and UPRTS over years. We find the performance of UPBTS and UPRTS are good in general but still have a potential scope for improvement. We also quantitatively analyze the reasons for inefficiency of them in some years and provide potential improvements for inefficient units. Moreover, we observe the efficiency of UPBTS is better despite a good development trend in the efficiency of the UPRTS. We demonstrate the UPRTS during the period 2006-2011 works on decreasing returns to scale (DRS), which indicates the authorities should adjust the UPRTS structure and improve the operational services without blindly expanding the levels of inputs. Our work may help in evaluating the possible enhancement of the operations of the UPTS.

Authors: Peřinková Martina , Česelský Jan , Řezáč Miloslav
Published: January 2014

During the 19thcentury, European cities witnessed radical reconstructions which were usually necessitated by the remarkable increase in traffic. The existing transport systems were often based more on Gothic period or even earlier. The narrow streets were no longer able to accommodate the increasing frequency of vehicles, which have been even more intensified by the development of railways. The second half of the 19thcentury and the period of the beginning of the World War II brought the construction of ring roads based on the layouts of former medieval walls and in big cities then more and more thoroughfares. Along these main avenues, mainly residential houses or parterre intended for services and trade were built, that nowadays form the traditional urban structure. The objects were not usually uniformed in style and in the 19thcentury there were mostly eclectic forms of architecture. In the early 20thcentury and at the turn of the century then we can meet the Art Nouveau style, Traditionalism, Cubism, Modernism and Functionalism.
Urban Bicycling and its Contribution to Transportation Sustainability: Comparison between European and Chinese Cities
Authors: Phan Maily Teresa , Wang Rong Chang
Published: January 2014

With todays challenges of global climate change, cities increasingly regard bicycling as a means to promote urban sustainability, liveability, and public health. Copenhagen, which not only was voted as the "Best City of Cyclists 2012", but also as the "Worlds Most Liveable City 2012", is a city of great inspiration. Copenhagen is popular for its current bicycle culture, but China has in fact also had a long history of bicycle use and was in the 1980s known as the "Bicycle Kingdom". Unfortunately, this reputation has foregone as a result of strong economic growth, increased urbanization and expanded city areas leading to rapid motorization and car-dependence. This research will highlight the bicycle development in China and make a comparison of the situation in Copenhagen and thereby to find suitable future suggestions for urban planners and transportation designers for urbanization of China.

Authors: Qiu Bo , Jin Zhi Hong
Published: January 2014

Dock congestion has been becoming increasingly troublesome problem in some regional hub ports in China, resulting in additional operational costs to feeder line shipping companies. To reduce the waiting times at the hub and to lower the operational cost, some companies place a pontoon close to the hub port as floating container terminal to berth smaller containerships. We discuss the justification for setting pontoons close to the hub from the viewpoint of a shipping company, propose a berthing decision model and describe a modified genetic algorithm to optimize the process. Simulation tests show that pontoon setting and rational scheduling can greatly alleviate congestion at the regional hub.

Development and Evaluation for Microdamage of Concrete under Uniaxial Compressive Load
Authors: Wang Yu Tian , Chen Wei Zhen , Jiang Fu Xiang
Published: January 2014

Development of microcracks and microstructures under uniaxial compressive load were studied by the measurement of axial residual strain and the calculation of specific crack area. Two opposite mechanisms could be distinguished for describing the development of microstructures, i.e. densification and micro-crack formation. Based on the experimental results, consistent tendency was found for the development of inside microcracks and overall deformation. Higher load level induced larger residual strain and residual specific crack area after unloading. Significant difference in the development of cracks was found for concrete specimens of different proportions. Specimen with higher water to binder ratio and lower strength developed earlier corresponds to lower initial stress-strength ratio for the beginning of crack propagation, and lower critical stress level for the beginning of unstable development. Effect of uniaxial compressive load on the durability of concrete specimen depends on the relative relationship between the two mechanisms.

Published: January 2014

In order to study the major affecting factors of commercial housing prices along rail transit lines, the paper chooses samples of commercial housing prices along the Beijing Subway Line 5, and uses 11 elements of location, structure and neighborhood factors as independent variables and housing prices as dependent variable to construct the housing hedonic price model. Make regression analysis by using SPSS software, and come to three major affecting factors and their influence degree which are distance from the nearest subway station, whether there is a hospital nearby and distance from CBD. In the planning and construction of rail transit, the coordination and convergence of subway stations, commercial housing and hospitals should be a serious consideration to improve the driving effect of rail transit on real estate.

Biological nutrient removal (BNR) is generally integrated in municipal wastewater treatment plants to alleviate the impact of treated effluent on receiving watersheds. This paper studies the performance of BNR in a membrane bioreactor system consisting of anaerobic, anoxic, micro-aerobic and aerobic compartments treating a synthetic wastewater containing low organic matters. The membrane bioreactor system designed an anti-stream, stepwise return flow scheme to produce ideal conditions for the occurrence of simultaneous nitrification and denitification and denitrifying phosphorus removal processes. The proposed membrane reactor system has established higher biomass concentrations and ideal environments for biological nutrient removal processes, which results in high nutrient removal efficiencies treating low organic wastewaters. Four compartment configurations in the reactor system minimized the impact of oxidized nitrogen species in return flow on phosphorus release in the anaerobic tank and the anti-stream, stepwise return flow scheme encouraged the utilization of nitrate as the electronic acceptor in phosphorus uptake in the micro-aerobic tank. Denitrifying phosphorus removal and simultaneous nitrification and denitrification processes are the main mechanisms responsible for efficient nutrient removal. High phosphorus release activities and high phosphate concentration in the anaerobic tank make it is potentially feasible to recover phosphorus resource from wastewater.
Study on Internal Layout of UK's Day Care Unit for Older People
Authors: Wei Da Ke , Jin Hong , Mei Hong Yuan
Published: January 2014

This study focuses on the internal layout of premises of UKs day care unit for older people, including possible combinations of rooms and spaces, access and circulation. All day units require a minimum of a dining/activity space, a kitchen, (a) toilet (s) and storage space, these rooms and spaces are combined into the basic type of premises. Depending on the aims of the unit, the number of places provided, and users' needs, many of the disadvantages associated with basic premises can be overcome if the premises have extra spaces. From the above analysis we can see that, in existing day unit premises, the number and type of rooms and spaces and how they are grouped together vary considerably, ranging from simple to complex arrangements. Also, the relationships between rooms and spaces in layouts for all day unit premises need to be pondered over, including distances between key rooms/spaces, the relative location of spaces in terms of their functions, the relationship between private and public spaces and the views within and between rooms, and from external windows. In addition, access and circulation of a day unit need to be considered carefully, including access to the day unit premises and the reception space and internal circulation.
