Vehicle-track dynamic interaction analysis of a metro vehicle
Authors: Han Junchen , Jiang Yongzhi 
Published: April 2020

Abstract
In this paper, comparison of results between the self-programming model (considering the track flexibility) and SIMPACK model (considering only fastener support) is carried out. The wheelset vibration is more obviously for the self-programming model as the track flexibility is considered. For the traditional dynamic calculation, the SIMPACK multi-rigid-body model is acceptable. Two kinds of harmonic vibrations in the car body for a metro car, which were found in the service operations, are reproduced by using self-programming model. High tread conicity leds to the harmonic vibrations in the car body about 4.8Hz. Reducing wheel conicity can improve the bogie hunting stability, and solve this problem. Another harmonic vibration with the frequency of about 2.2Hz in the car body is caused by the constant excitation wavelength in the track, which causes vibration transmited through the primary and secondary suspensions to the carbody. To reduce this harmonic vibration, more advanced suspensions are needed.

Comparison and correction of element measurements using XRF core scanning and ICP-AES methods in lacustrine sediments
Authors: Cheng Aiying , Yu Junqing , Gao Chunliang , Zhang Lisha 
Published: April 2020

Abstract
An integrated analysis has been carried out on core dated by qualitative X-ray fluorescence core scanning combination of quantitative ICP-AES in order to characterize the extent of elements Cd, Cr, Cu, Zn, and Pb in the Lake Toson in the northeastern Tibet Plateau. When combining both the quantitative and qualitative measurements, we observed a significantly positive correlation. Comparing the ratios between element intensities and concentration, we found that the XRF element intensities were related to the amount of water. Using the intensity of Cl as an indicator of water content, the element intensities of Cd, Cr, Cu, Zn, and Pb in the core samples were corrected. The correlation coefficients of each pairs of the two datasets among Cd, Cr, Cu, Zn, and Pb were significantly raised. These data sets with highly correlations were used to produce a transfer function to relate XRF element intensity with element concentration. Calculated element concentrations from the intensities show only minor differences from concentrations obtained by ICP-AES, indicating XRF core scanners are a very useful tool for measuring element concentration in lacustrine sediments.

Published: April 2020

Abstract
This paper established the disequilibrium degree model of effective supply and effective demand in the assembled property market. Based on the statistical data from 2001 to 2018, the paper estimated and tested the parameters of the disequilibrium model of effective supply and demand, and calculated the disequilibrium degree of effective supply and demand in China’s assembled property market. The results indicated that China’s assembled property market was not effective and equilibrium, but obviously imbalanced and fluctuated. The research results provided strong empirical evidence for revealing that price distortion was one of the important factors causing the disequilibrium in China’s assembled property market. In order to develop healthily and improve the level of social welfare, the government should take it as a basic policy in the future to eliminate the disequilibrium of effective supply and demand in the assembled property market.

Authors: Li Bin , Chen zhijun , Liu Zhao 
Published: April 2020

Abstract
Based on the actual project, through the simulation of the construction steps and the inversion analysis of the monitoring data, the settlement of immersed tube tunnel is predicted. Through analysis, it is found that the whole foundation soil layer of immersed tube tunnel appears rebound, the maximum rebound is 0.045m, and the maximum rebound appears on the surface of the foundation trough. As the depth of the soil deepens, the rebound decreases gradually. After the construction is completed, the vertical strain curves of the immersed tube model are all distributed in a saddle shape. After the immersed tube strain is stable, the strain variables of the immersed tube increase with time basically unchanged. 1000 days after the completion of backfilling, the maximum post-construction settlement is 0.0035m.
Safety Risk Analysis of Bridge Rhombic Hanging Basket Construction Based on WBS-RBS and Rough Set Theory
Authors: Li Qingfu , Qian Huajie , Pei JunJie , Wang Saisai , Lei Jia 
Published: April 2020

Abstract
Because of its simple structure, light static load and no balance-weight, the rhombic hanging basket has become one of the most widely used forms in bridge hanging basket construction. In the construction process of rhombic hanging basket, there are often high risks and hidden dangers, which may cause serious engineering accidents and losses. If we can analyze these risks in the early stage of the construction of hanging basket, we can not only provide security for the construction process, but also provide basis for the construction safety management. In this paper, a comprehensive evaluation model is established by using Work Breakdown Structure- Risk Breakdown Structure and rough set theory. This model uses WBS- RBS coupling to form the association between the construction risk and the operation activities of the hanging basket, and the risk decomposition matrix is constructed to identify the risk of the whole hanging basket construction process in detail, and each risk factor is corresponding to each bottom work package. Then, rough set theory is used to determine the weight of risk in each underlying work package. Finally, the risk degree of each operation unit in the construction process is sorted according to the weight value of the risk contained, and then the high-risk links in the construction process of hanging basket can be clearly understood, so as to provide basis for construction risk management.

Abstract
Based on the LANDSAT remote sensing image data of 2000, 2005, 2010 and 2015, this paper applies RS, GIS, mathematical statistics and other methods, mainly about land use transfer matrix, single land use dynamic and comprehensive land use dynamic to analyse land use change in Jining City during the period from 2000 to 2015. The results show that: (1) The transfer intensity of grass is gradually increasing. Dry land and house-site in the countryside are transferred largely into town house. The transfer between dry land and house-site in the countryside is obvious. The imported area of waters is always larger than the exported area in three periods. Retention rate of dry land has remained relatively high. In addition, the unutilized land retention rate varies greatly. (2) The single dynamic of paddy field, town house and unutilized land are large, indicating changes of these types are intensive; the lower dynamic of dry land and waters indicates the stability of these types is good. The comprehensive land use dynamics first decreased and then increased, indicating that the intensity of land use change in Jining City first decreased and then increased, and the overall land use change is large.
