Published: March 2013

For Magnetic Suspension Gyro-total-station has vulnerable to outside interference factors, there are some random drifting containing in measurements which are unable to establish its mathematical model. Vondrak filter which does not require the model is used to pre-process measurements of Magnetic Suspension Gyro-total-station. In this paper a high-precision astronomical baseline is established in Xi'an, and the gyro azimuth is tested eight times in baseline. 40,000 north-seeking torque of the first and second place is filtered by the Vondrak filter for each test. The results show that the burr of data is reduced after filtered, and the filtered values reflect the trends of gyro north-seeking. Compared with the root mean square (RMS) of the measurements, RMS of Vondrak filter is decreased, the data is denser. Vondrak filter can effectively eliminate the random drifting containing in measurements, retain useful information in the maximum extent, and improve the accuracy of true north azimuth.

Authors: Liu Yuan Wen , Ren Xiao Feng
Published: March 2013

Environmental vibration problem caused by rail transport is always a crucial problem for the development of rail transport harmoniously and favorably. Lots of legislations have formulated to constrain this problem in many countries, however, most of them are worked out based on the analysis results and measured data from only single rail line. With the further development of rail transportation in China, more and more engineering will cross the others inevitably, which will cause a more complicated problem with multi-vibration source. And obviously, the multi-vibration source problem is not the linear superposition of several single vibration source problems. Focusing on two being planned overlapping shield tunnels, the computation model is established and the environmental vibration is calculated and analyzed by considering the running mode and running number of subway train. Fitting analysis is conducted and empirical formulas for vibration attenuation and then, the vibration range is determined accordingly. The research results in the paper can provide guide for the pre-design of overlapping engineering and also can offer references for the completion of relative legislations.

A new type of reinforced concrete (RC) structure termed concrete filled fabricated concrete tubular (CFFCT) was economically evaluated. Construction schedule time and construction cost of CFFCT and RC columns were analyzed both in case studies of building structure and bridge structure. A comparative analysis was done on two types of columns by studying on single column and present value of total construction cost. The results show that use of CFFCT shortens the construction schedule time and lowers the total construction cost. The investigation of the multistory building shows that using CFFCT results in an average of 2.31% savings on total project cost, an average of 28.67% savings on total column costs, 25.12% savings on total project time period, and 45.22% savings on columns construction time period. And the investigation of the bridge shows that using CFFCT results in an average of 3.27% savings on total project cost, an average of 46.87% savings on total column costs, 15.68% savings on total project time period, and 29.90% savings on columns construction time period.
