节理网络有限元在倾倒斜坡稳定分析中的应用

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。

Application of finite elements with joint net to stability analysis of toppling slope

The finite elements with joint net is a powerful program which has the function of modeling actual joint net of rock mass slope,it not only permits in-situ statistic parameters of the joints to be input into the model directly,but also gives joints the right to yield according to a certain criterion and thus can better simulate the real rock mass structure of the toppling slope and failure pattern.The stability analysis method of the toppling slope and open questions are discussed;the function and input par...
