摘　　要：介绍白莲河地下主厂房出露的F8断层,斜切洞室顶拱、上游边墙及岩壁吊车梁岩台,对围岩稳定产生的不利影响。采用分段开挖支护、长锚杆及锚索加固、固结灌装、格构梁喷护、排水等工程措施进行综合处理,并审慎监测,以确保洞室围岩稳定。That fault F8 appearing at Bailianhe underground powerhouse crosses over the vault, upstream sidewall and the rock runway is disadvantageous to the stability of the surrounding rock. Various engineering measures are used to ensure the surrounding rock stability, such as, excavating and supporting the powerhouse sectionally, strengthening the surrounding rock by long anchor bars and cables, consolidation grouting, shotcrete framework supporting, well draining and carefully monitoring.
