Shield Worn Bridge And Highway Engineering Risk Analysis And Research On Numerical Simulation

At present,China's many cities are in the construction of the subway,a large number of subway tunnel construction by shield method,shield tunnel construction will inevitably built nearby,or pile foundation.In recent years,accidents of similar projects have also demonstrated the necessity of risk research on the construction of structures under shield construction.This paper takes shenyang subway project as an example,the side wear of shield tunnel bridge pier and assess the risk and research of highway engineering.In this paper,based on three main methods: the study of the engineering risk theory research analysis,numerical analysis and in-situ measurement analysis method,the side wear of shield tunnel construction risk evaluation on the bridge pier and highway engineering and research,taking a subway project in shenyang as an example,based on the geological exploration data,design data,the numerical analysis method,the application of MIDAS-GTS software,to simulate the shield side wear under the bridge pier and highway,comprehensive consideration,space effect,the geological conditions of excavation method influence factors,such as tunnel excavation on existing Bridges and roads are analyzed.The actual results of the project are compared with the simulated values,and the data results are small.The conclusion of the project and could be a reference for the construction of similar engineering.
