Numerical Simulation of Monitoring Technology for Foundation Pit Construction Based on Water Rich Sand and Pebble Strata
There are always certain safety hazards in the dewatering and excavation of foundation pits during urban rail transit construc-tion.Therefore,in order to avoid safety accidents,the Abaqus two-dimensional finite element model is used to monitor the construction of foundation pits,and its effectiveness is verified through experiments.The experimental results indicate that in the comparison experi-ment of the settlement values of the surface outside the pit,the error between the simulated monitoring values and the actual monitoring values remains between 2% and 5%,while the error in the comparison experiment of the horizontal displacement of the enclosure structure remains around 10%.
