Simulation and prediction study on the effect of pitfall on seepage field during metro space construction
In order to simulate and predict the stability of underground water layer structure,so then ensure the safety of subway construction process,a geological hydro-logical model was constructed to analyze and test the performance of three foundation pitfall schemes.The research results indicate that under the waterproof curtain,the radiation well rainfall scheme maintains a drainage time of 5～12 days with a maximum total pumping capacity of 291 279.124 m3 when the diameter of the radiation pipe is0.1～0.3 m.The practical results have proven that the radiation well rainfall scheme under the waterproof curtain has better rainfall effect and higher application value,which is helpful for improving the stability of underground geolog-ical and hydro-logical results in subway space construction.
