Analysis on the mechanis m and prediction of water -inrush under high -pressure in Daxiangling Tunnel
摘要
Abstract
The potential critical positions of water inrush in the deep,long and high pressure tunnel are mainly located on the fault areas or the influenced zone.So the prediction for the high -pressure water inrush on the fault has become a key technology problem for tunnels and other underground constructions.Based on the analy-sis of underground storing space,water passage,water discharge,water head distribution and hydraulic gradi-ent,we evaluated the water -inrush risk on each fault area.Considering the main influence factors of water -in-rush,it is divided into three models:a)direct inrush model,b)erosion inrush model and c)rupture inrush model.The essential conditions and water -inrush possibility for each model on the fault area were discussed. Moreover,the water -inrush risk was forecasted comprehensively under the high -pressure.关键词
