干燥与饱水状态下砂岩的剪切蠕变特性研究
Shear creep characteristics of sandstone under dry and saturated states
摘要
Abstract
Taking Wuhan Yangtze River tunnel as the project background, the shear creep tests on dry and saturated sandstones are conducted. Based on the test results, the effect of water on shear creep characteristics of sandstone and its mechanism are elaborated from both shear creep strain and mechanical properties. The results show that water can promote the development of creep strain and accelerate creep strain rate of sandstone and also decrease its creep rupture strength. Therefore, the effect of water on the creep characteristics of sandstone can not be ignored in the engineering design and construction of important project.关键词
