构皮滩双曲拱坝三维地质力学模型试验研究

Three Dimensional Geomechanics Model Test for Goupitang Hyperbolic Arch Dam

采用三维地质力学模型试验技术，研究了构皮滩双曲拱坝坝基内的层间错动带和裂隙对坝体和坝肩稳定的影响，以及在超载情况下坝体的破坏形式和坝肩的破坏发展过程。最后对大坝的安全性作了评价。

Through three dimensional geomechanics model test, the effect of interlayer staggered zones and fissures in the dam bedrock on the stability of the Goupitang arch dam and its abutments, the failure style of the dam mass under overloading condition, and the development process of the failure in the abutments, were studied. Finally, the safety of the dam was evaluated.
