摘要：A new uncoupled method is presented to simulate rock failure process, i.e., the nonuniform grids are introduced into REPA (rock failure process analysis)system to develop some models by virtue of the excellent preprocessing functions from other commercial softwares for numerical simulation. Then, the information on the models already developed, elements, material properties, etc. is provided for RFPA system to calculate or postprocess them. To verify RFPA's reliability, this new method is contrasted with the original RFPA that based on uniform grids. Some analytic examples are given and the results show that this method not only break through the limitation of grids and models in the original RFPA but also is easy to operate. It is therefore regarded as a new way to numerical simulation worthy to apply it to rock and soil engineering and spread it out.
