| 摘 要： | 复杂地质特征给数值模拟的建模工作带来很大困难,针对该问题,提出并实现了岩体结构三维无缝建模方法.将直接法拓展到四面体网格剖分中,实现了基于岩体结构无缝模型的四面体优化剖分方法,从而为数值模拟提供既符合地质实际,又有较高网格质量的计算模型.利用该方法建立了某拱坝坝肩岩体三维地质模型,并进行四面体优化剖分.

| Abstract: | It is difficult to build geological models for numerical simulation when meeting complex geological structures.In order to address this problem,a seamless modelling method for rock-mass structure is proposed and realized.A method for optimizing tetrahedral mesh generation based on the seamless geological model is also realized by developing direct method.Combining these two methods,a numerical model,which is coincident with geological realities and having optimizing mesh,can be built for numerical simulatio... |
