本文介绍了国内某大型双曲薄拱坝的整体地质力学模型破坏试验,此次试验采用了严格地模拟岩体的技术。比较全面地反映了岩体的力学特性并采用了国内最大比尺。本次试验比较详尽地观测了大坝及坝肩的变形破坏机制。从而为设计提供了安全度及大坝承载能力的依据。这是以往地力学模型所难以做到的。
This paper introduces the overall geomechanical model failure test of a large hyperbolic thin arch dam in China. This experiment adopts the technique of strictly simulating the rock mass. More comprehensively reflects the mechanical properties of rock mass and adopts the largest scale in China. This experiment observed the deformation and failure mechanism of dam and abutment in more detail. Thus providing the basis for the design safety and dam carrying capacity. This is difficult to do with previous geomechanical models.
