基于强度试验的胶凝堆石材料破坏准则
The failure criterion of cemented sand and gravel material based on strength test
摘要
Abstract
Based on compression tests, tension tests, and large scale three-axis tests on cemented sand and gravel(CSG) materials, the basic mechanical properties of CSG materials were systematically studied and the stress intensity of CSG was obtained during the CSG failure process. The correlativity between the failure strength of CSG materials and the ambient pressure was analyzed. According to the correlativity, the failure criterion of CSG materials with a cement proportion of 60 kg/m3 was established. The failure criterion of CSG materials with different cement proportions was established by fitting data of the failure strengths of CSG materials, the ambient pressures, and the cement proportions. The results show that the failure criterions of CSG materials have good performance, and show better support ability for similar applications development.关键词
