摘要

以武汉越江隧道为工程背景，对干燥和饱水砂岩进行了剪切蠕变试验，并从剪切蠕变应变特征和剪切蠕变物理力学特性两方面进行了对比分析，重点阐述了水对砂岩剪切蠕变特性的影响，同时对其影响机制进行了相应的分析。结果表明，水能够增大砂岩的蠕变应变量和蠕变应变速率，并降低蠕变破坏强度值。因此，在重要工程设计和施工中，不能够忽视水对砂岩蠕变特性的影响。

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.
