摘要
综述了应用固体力学连续介质理论分析大地构造运动的问题,讨论了它们和通常力学问题的差别。主要的不同在于这里是反演问题:从地表的大地构造表现模拟出内部过程,从当前的资料追索它们的历史。依靠地球科学家所收集到的资料来引导这些反演。在数值模拟中建立适当的本构关系和破坏准则是头等重要的环节。最后提出固体力学中有关的研究课题。
Problems concerning the use of the continuum theory of solid mechanics to analyze the tectonic movements are reviewed. The difference between these problems and ordinary mechanics problems are discussed. The main difference is that the problems here are inverse ones, from the surficial manifestation of tectonic movements to model the interior processes, from the present information to trace their histories. Informations gathered by Earth scientists are to be used to guide the inversion. The establishment of proper constitutive relation and rupture criterion is of paramount importance in the numerical simulation. Challenging problems in solid mechanics are mentioned.
