A survey was designed to investigate opinions on railway trespassing of people living close to a railway line. The results showed that 89.2% of the respondents (n = 502) recalled that they had seen trespassing in their neighbourhood and, based on their observations, adults are the largest group trespassing. Overall, 68.9% of the respondents had personal experience of trespassing although 83.5% ...

The construction scale of the shield tunnel underpass is expanding day by day. In order to study safety influence and deformation control on existing tunnel, LSSVM model established. Based collected soil storage pressure, foam volume, simultaneous grouting volume other six parameters corresponding sample data bottom displacement, horizontal displacement settlement caused approach are predicted....

The settlement of track in a railroad underpass project was studied by theoretical analysis and numerical simulation, based on the model winkle beam elastic foundation. Taking roadbed as nonlinear boundary condition, control differential equation large deformation established solved Fourier series method; solution obtained establishing an actual compared analyzed with cosine function solution. ...
