摘要本文作者对当前岩石力学发展中的若干关键问题提出了自己的看法和建议。其中首先涉及到高地应力对软弱围岩稳定性和硬质围岩的稳定性问题。第二方面涉及节理裂隙岩体和某些非线性软弱围岩及支护的研究。这其中涉及到复杂岩体的破裂机制和施工过程的影响。第三方面对模型试验方法的作用做了论述，并建议应着重在数值分析效果不佳的问题上采用模型试验。第四方面对于数值分析方法存在的问题作了评述，指出它们分别适用的条件、存在的问题和可能解决的途径。特别指出当前非连续介质分析法不能解算大工程问题的解决思路，还对复杂岩体的本构关系、今后研究的思路提出了建议。最后对其它几个热点和难点问题谈了认识和建议，包括工程岩体稳定性的判据、应发展非确定性方法作为围岩稳定性判据，及用非连续分析法分析节理岩体进行真正裂隙网络固流耦合模型的渗流问题研究等。

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
