摘要
根据三峡工程永久船闸地质勘探中获得的花岗岩岩石，采用了有效的加载方式，模拟了现场岩石节理情况，进行了岩石拉剪蠕变断裂的试验研究，研究了花岗岩在拉剪应力作用下的蠕变变形规律，蠕变模型的建立等，为三峡工程的建设提供有效的数据和资料．
The importance of rock tension-shear and creep rupture study is discussed. By using the cores cut from rock mass, different dimensional specimens are tested under different stress combination. According to the test results; the creep relations of rock under tension-shear are studied and the model of creep is built etc. This experimental research provides effective data for the construction of the Three Gorges project.
