加筋土格宾围堰是一种新型的围堰型式,其具有结构简单、稳定性好、施工方便、适用面广外形美观等特点.结合土谷塘航电枢纽工程一二期共用加筋土格宾纵向围堰的工程实际情况,建立了加筋土格宾纵向围堰的二维有限元模型,对其进行了二维有限元分析,分析其在施工工况和正常运行工况下围堰堰体的应力应变规律,并指出薄弱部位,并对施工应关注的问题进行了深入探讨.%Reinforced soil of cofferdam is a common cofferdam type. Its characteristics included simple structure , good stability, easy construction and wide range of beautiful appearance. Based on physical circumstances of longitudinal cofferdam of reinforced soil second-stage cofferdam of Tugutang navigation-hydropower junction, the two-dimensional model is established, and two-dimensional nonlinear anslysis is proceeded. And then the stress-strain regularities of distribution and weak regions of cofferdam are reveald when the cofferdam are in construction and normal working. And last, the problem that should be concern about in construction is carried out discuss thoroughly.
