【摘要】 70年代发展起来的散体单元法是一种适用于节理岩体稳定分析的数值计算方法。本文阐述了散体单元法的基本理论及其在岩体稳定分析中的应用,借助于计算机和CDA技术,不连续岩体的破坏过程、应力应变场、位移场及力场的分布可以迅速直观地显示出来。本文介绍了作者用散体单元法进行岩体抗滑稳定的初步研究,并用高速摄影机和激光散斑方法做了验证试验,计算结果和试验有着相当好的吻合。更多还原

【Abstract】 The discrete element method,which has been developed since the seventies,is a numerical method suitable for analysis in jointed rocks.The fundamental theories of the discrete elemnt method and its application in analysis of rock mass stability are described in this paper.By means of computer and CAD technique,the failure process of discontinuous rock mass and distribution of stress-strain field,displacement field etc,can be displayed easily and promptly,The preliminary research of resistance to slide of rock masses by using discrete element method is reported in this paper,the comparative tests by using high-speed camera and laser speckle method have been done.The calculation results are quite in accordance with the model tests.更多还原
