摘要： 提出了一个新型的能够分析岩石局部破坏过程的非耦合方法,即在岩石破裂过程分析系统(RFPA)中引入非均匀网格,利用其他商业数值模拟软件的优秀前处理功能进行建模,把建好的模型信息导入到RFPA中进行计算和后处理.为了验证程序的可靠性,同原RFPA均匀网格做一个简单误差对比.最后给出一些计算实例.结果表明,此方法不仅突破了原来RFPA的网格和模型的限制,而且操作简便,是值得岩土工程应用和推广的新型数值模拟方法.

Abstract: 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.
