土石坝心墙槽孔开挖导致上游坝坡变形机理分析
Mechanism analysis of upstream dam slope deformation caused by excavation of core wall slot in earth-rock dam
摘要
Abstract
Plastic concrete anti-seepage walls have outstanding anti-seepage and strain resistance capabilities,and are widely used in anti-seepage engineering of dangerous reservoir dams.During the construction of plastic con-crete core walls to reinforce earth-rock dams,although slot excavation has been carried out by staggered construc-tion as required,there are still multiple earth-rock dam reinforcement projects that have experienced sudden land-slide during slot excavation construction.Specifically,the landslide on certain dam slopes did not occur on the downstream slope,but rather on the upstream slope.In response to this issue,taking the landslide on the upstream dam slope during the slot excavation of the Wenbian auxiliary dam in Tunliu Reservoir as an example,through on-site investigation and numerical simulation,the deformation mechanism of landslide on the upstream dam slope was analyzed.关键词
