Hardfill坝结构破坏模型试验研究
Study on structure failure test of Hardfill dam
摘要
Abstract
Hardfill dam is a new type of dam.It is necessary to study the structure failure mode and mechanism,and also to estimate structure safety for promoting the development and application of the new dam type.Based on geomechnical model test,the first domestic failure model experiment of Hardfill dam was carried out to analyze the deformation and failure characteristics of the dam due to load.Results show that failure areas of typical Hardfill dam were located in dam heel,toe and the interface of the dam and foundation.During the overload process,the dam experienced three typical stages:stable,nonlinear deformation and failure.The failure mode was concluded as dam heel cracked firstly and then dam toe damaged,finally the dam integrally slid along the interface of the dam and foundation.Meanwhile,triangle blocks were separated from dam body resulted from the cracks in dam heel and toe;cracking overload safety K1 of dam heel and toe was 6.0 to 7.0,large deformation overload safety K2 was 7.5 to 8.5,and eventually failure overload safety K3 was 9.0 to 10.0.关键词
