摘　　要：官地水电站左岸导流洞地质条件复杂,洞身设计开挖断面大,前期勘探F8断层的出露与实际出露位置相差较大,F8断层走向与产状对洞身稳定影响较大。该断层施工处理进度紧张,在施工过程中,密切结合实际,深入进行技术和方法研究,对施工期临时支护采取了边施工、边设计、边总结的动态优化处理方案,切实有效,安全、快速的完成了F8断层处理施工。Geological conditions along diversion tunnel at left bank of Guandi hydropower station is relatively difficult and the tunnel section is designed to be large . Outcrops of F8 investigated initially are located quite far from the real outcrops and strike and occurrence of F8 are very much important to the tunnel stability. Construction schedule for treating this fault was very tight. During construction, close attention was paid to actual site condition and relevant technologies and methods were developed further. The dynamic optimized treatment option was selected for the temporary supports which were designed,constructed and summarized whenever necessary,therefore F8 treatment was completed effectively, safely and rapidly.
