摘　　要：山西中部引黄工程总干3#隧洞下穿北川河段,开挖过程中由于地下水影响,多次出现突泥、涌水等不良地质情况,并伴随发生两次高速公路路面塌陷。文中通过单孔、多孔、群孔抽水试验等试验方法,论证地表大口井降水的可行性。In the middle of Shanxi,the Yellow River Diversion Project,3#tunnel underruns the Beichuan River.During the excavation process,due to the influence of groundwater,unfavorable geological conditions such as mud burst and water gushing occurred repeatedly,and two highway road collapses were accompanied.By means of single-hole,multi-hole and group-hole pumping tests,the feasibility of water drawdown on large diameter wells is demonstrated.
