摘要
本文根据三峡工程永久船闸区地质勘探中的花岗岩岩芯 ,通过非对称切口试件来模拟岩体的拉剪作用的实际情况 ,对岩石拉剪力学特性进行了试验研究 ,探讨了岩石的单轴受拉强度、拉剪联合强度、应力应变关系、破坏形式及破坏准则等 ,为三峡工程建设提供了有价值的数据和资料。
By using the rock cores from the geological investigation in Three Gorges Project, the actual condition of rock acted by tensile-shear stress is simulated in this paper. The tensile shear properties of the rock including the uni-axial tension strength, the combined tension-shear strength, the stress-strain relation, and the failure criterion and failure mode are studied. Many valuable data and information are given to the construction of the Three Gorges Project.
