According to in - situ construction real time observation and inverse analysis results , refinement numerical artificial analysis on a group of headrace tunnels was conducted and influence of different construction schemes and support parameters on rock mass deformation and failure behavior were researched to provide quantized data and technical aid for project construction decisions 基于跟蹤施工的現場實時觀測和反演分析結果,對引水發電洞群進行了精細化數值仿真分析,研究了不同施工方案和支護參數對巖體變形、破壞特性的影響,以便為工程的施工決策提供量化資料和技術支持。

Due to complex and varied geological conditions for 4 headrace tunnels at zipingpu project , real time monitoring technique was used during informatization construction according to new austrian tunneling method , system observation for typical sections was conducted by following in - situ construction , based on which inverse analysis for rock mechanics parameters was conducted 針對紫坪鋪工程4條引水發電隧洞復雜多變的地質條件,采用新奧法隧洞信息化施工中倡導的實時動態監測技術,跟蹤現場施工進行了典型斷面的系統觀測,在此基礎上進行了圍巖宏觀力學參數的反分析研究。
