摘要
东山供水工程隧洞塌方段长38.22 m,塌方区上部为松散体、空腔。揭露的地质情况为含砂低液限黏土层,地下水位线位于洞顶之上。该塌方处理采用混凝土灌注桩型式的止浆墙封闭掌子面,为塌方区安全处理提供了保障。
The length of tunnel landslide section of Dongshan Water Supply Project is 38.22 m,and the upper part of the landslide area is loose body and cavity.The geological situation revealed is a sand-bearing low-liquid-limit clay layer,and the groundwater level is above the cave roof.The landslide treatment uses a concrete-filled pile type grouting wall to close the driving face,which provides a guarantee for the safe treatment of the landslide area.
