摘要:
随着寒区或特殊施工环境条件下基础设施建设的需要,人们越来越发现有必要对冻结岩石力学问题进行深入的研究。以从胡家河矿井筒冻结现场选取煤岩及砂岩2种具有代表性的岩样,在MTS815实验机上进行不同围压及不同温度条件下的单轴及三轴压缩实验,分析煤岩及砂岩在相同围压不同温度条件下及相同温度不同围压条件下的强度特性,并对2种不同岩样的同一性和差异性进行了比较研究,推导了含温度因子的冻结岩石非线性破坏准则。为低温条件下岩石力学特性研究提供参考。
Abstract:
With the demands of fundamental construction of infrastructural acilities, it is necessary to research the problems occurred on frozen rock mechanics in cold regions. In this paper,two typical soft rocks coal-rock and sandstone were obtained from engineering sites of Hu Jia river coal mine in Shaanxi Bingchang mining area. The uniaxial compression tests and tri-axial compression tests were conducted on the two types of soft rock at different frozen temperature and different confining pressures. The strength and deformation characteristics under these conditions were analyzed. And their identity and difference were compared. Considering the mentioned before,a new non-liner failure criterion was educed.The study is of a significant reference for freezing rock mechanics.
