摘　　要：龙滩水电站输水发电系统洞室群是结构复杂的巨型地下工程。洞室群围岩为陡倾角层状岩体,围岩的稳定性是工程建设的关键问题。针对围岩稳定性和支护处理,在工程勘测设计阶段先后进行了大量的分析研究工作,在工程施工初期又进行了科研攻关,为全面论证该巨型地下工程围岩稳定性提供了有力的技术保障。The excavation for water conveyance and electric power generation system is a gigantic underground works with complex structure in Longtan Hydropower Station. Surrounding rock of underground works is in steep dip and sill like, so that its stability is the key to the project during its construction period and in future. A large number of analytical investigation were carried out aiming at the stability of surrounding rock and its support during its exploration survey and design phase, and as well as scientific researches of tackling key problem were conducted at initial stage of construction. The results of these research efforts supply potent tech support for demonstrating the stability of surrounding rock to such as huge underground works.
