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.
