Abstract In this paper，the author puts forward its own views and suggestions in view of the several current key problems in the development of rock mechanics. First，this paper involves the stability problem of soft surrounding rock and hard rock mass related to high ground stress. Second，it studies jointed and fractured rock masses，some nonlinear weak surrounding rock and support，which deals with the fracture mechanism of complex rock mass and the influence of construction process. Third，the role of model test method is discussed，and the model test should be mainly applied in the problems，where the numerical analysis effect is not good. Fourth，the problems existing in the numerical analysis method are discussed，giving respectively applicable conditions，the existence question and the possible solutions，especially the solving thoughts that the current discontinuous analysis method cannot solve large engineering problems. Also for complex constitutive relation of rock mass，the research idea in the future are proposed. Finally，the author puts forward his own idea and suggestions on several other hot and difficult problems，including the idea nondeterministic analysis method as the criterial rock stability and discontinuous analysis method of seepage problems for the true stress-water couple model of jointed engineering rock mass should be developed.

Key words： discipline development key issues initial stress constitutive relation physical and numerical simulation
