节理网络有限元是指具有节理网络模拟功能的有限元,它不但能将野外节理统计特征直接输入到模型中,同时允许节理按一定的破坏准则产生屈服,从而较好地模拟边坡的实际结构及破坏特征。论述了倾倒变形边坡的分析方法及存在的问题,介绍了节理网络有限元的功能及参数输入,说明了其在倾倒变形边坡应用中的优势,并以黄河上游茨哈峡电站Ⅰ号倾倒体为例,计算了该倾倒边坡的稳定性及破坏趋势,结果表明,节理网络有限元是倾倒变形边坡稳定分析的一种有效、可靠的方法。
The finite element of the finite element network is a finite element with the function of joint network simulation. It not only can directly input the statistical characteristics of the field joints into the model, but also allows the joints to yield according to certain failure criteria so as to simulate the actual structure of the slope And destruction of features. The analysis methods and existing problems of dumping slope are discussed. The function and parameter input of the finite element of the joint network are introduced. The advantages of dumping deformation slope in application are illustrated. As an example, the stability and failure tendency of the slope are calculated. The results show that the finite element method of the joint network is an effective and reliable method for slope stability analysis.
