岩土结构中应变局部化有限元方法研究

Research on reacting partial changes limited unit methods in rock earth structure

介绍了岩土结构中常用的研究结构及其破坏机理的方法,通过对应变局部化的理论和数值模型的研究,初步探讨了改进控制方程、自适应技术和非连续形函数三种解决岩土应变局部化问题的方法,对研究结构破坏机理及解决实际工程问题都具有重要意义。

It introduces the common researching structure and methods which damaged its principles in rock earth structure. Through the research on reacting partial changes theory and numerous simulations, probes into three methods to solve the reacting partial changes of rock earth such as improved controlling formula, automatic suitable skill and non-continuous function. And it also has signifieance for researching structural damaged principles and solving actual project problems.
