摘要
结合三峡工程岩体本构模型、拉剪应力状态下岩体强度性质、裂隙岩体开裂机理、边坡岩体卸荷带范围划分以及长期变形稳定分析等复杂岩体力学问题的研究 ,总结了岩石应力应变关系全过程测试、岩体“拉剪”试验、岩石断裂韧度测试、岩体声波测试及现场岩体蠕变等试验新技术在三峡工程中的应用。
Through the research of complex rock mechanics problems of the TGP,including rock mass constitutive model,the properties of rock strength under tensile shear stress state,the mechanism of cracking in fractured rock mass,the classification of range of slope rock mass unloaded zone,the long term stability analysis of deformation etc.,the applications of new techniques of test in the TGP such as the whole process test for finding rock stress strain relation,the rock'tensile shear' test,the rock fracture toughness test,the rock sonic wave examination,the rock creep test in sita etc.,are summarized.
