Cause Analysis and Treatment Scheme of Mud Gushing in a Hydraulic Tunnel in Xizang
摘要
Abstract
The mudslide disaster that occurs when a hydraulic tunnel passes through a sandstone and mudstone formation seriously restricts the progress of the project and threatens construction safety.Taking a hydraulic tunnel in Xizang as an example,the causes of mud influx in the tunnel were accurately identified through the use of geophysical exploration and geological drilling methods.It adopts a treatment plan of backfilling with stone slag and reverse pressure grouting inside the tunnel,advanced support for large pipe sheds,advanced support for small conduits,steel arches,and short advance excavation support with reserved core soil method,which has successfully passed the construction of unfavorable geological tunnel section.关键词
