Pre-Grouting Treatment and Flow Numerical Simulation for the Landslide Area of Dalian Metro
The study discusses the simulation analysis based on the modflow software. Generalize body site, zone and boundary conditions of simulation, make a finite element model based on the geology of the Collapse of Lot 110 , Dalian Metro. Determine the accuracy of the simulation results based on the comparison between the test and the field measurement data. And then predict the flow of groundwater and the penetration. Base on the software simulation of the surface displacement and field observation wells pumping records, to calculate the water surface elevation and the elevation, the general trend of measuring is same and the values are consistent. Prove the necessity of the injection that is used in the accident.
