桐柏抽水蓄能电站围岩变形回归分析
Backward-analysis on Deformation in Surrounding Rock of Tongbai Pumped Storage Power Station’s Underground Factory
【摘要】 分析了桐柏抽水蓄能电站地下厂房开挖期间围岩变形特性,并采用岩体粘弹性位移反分析方法,反演得出地应力、弹性模量及粘性参数。该分析方法可指导围岩支护设计和后期或相邻工程的施工方案的改进。
【Abstract】 Deformation characteristics of surrounding rock of Tongbai Pumped Storage Power Station’s underground factory is analyzed.Geostress,elastic module and viscosity parameters are obtained by visco elastic and are analyzed backwardly.The results can be used as a guidance for the design of surrounding supporting rock and the scheme improvement of subsequent and adjacent construction.
