摘要
溪洛渡水电站地下厂房洞室群规模居国内已建和在建工程之首,洞室密集、边墙高、跨度大、交叉口多。分阶段对地下厂房洞室群进行了监测和反演分析,并运用其监测与反演分析成果对支护结构形式进行了优化,取得了可观的经济效益。经优化后的支护结构付诸实施后,实测最大变形59.8 mm,小于国内同类工程。洞室整体稳定性好。详细介绍了反演分析过程,对类似工程具有指导和借鉴作用。
The underground powerhouse caverns of Xiluodu Hydropower Station is the largest in the projects built or being built in China with the characteristics of intensive caverns, high side wall, large span and many intersections. The optimization for supporting structures gets considerable economic benefits on the basis of the results of monitoring and inversion analysis of under- ground powerhouse caverns stage by stage. After the optimized supporting structures were put into effect, the maximum deforma- tion is 59.8 mm, smaller than ones of similar underground powerhouse, and the overall stability of caverns is well. The process of inversion analysis is introduced in detail, and it provides the reference for similar projects.
