Impact Evaluation on the Pipe-jacking Crossing Safety of Subgrade behind Bridge Platform Based on Numerical Analysis
Taking the subgrade project behind the expressway bridge platform with the pipe-jacking crossing method for the tap water pipeline as the research case,the influence of crossing construction on the stability of the expressway subgrade and bridge is analyzed by using the finite element analysis software.Based on the numerical analysis result,the suggestions for the influence degree and safety protection measures during the crossing construction are put forward,so as to ensure the safety and stability of the expressway and bridge structure during the construction.
