根据黄土地震滑坡的几何统计特征和物理力学性质,总结提出一种新的三维滑坡模型,并采用归一化三维矩阵的表示形式。借用遗传算法(GA)的核心思想,以归一化三维矩阵中的第三维元素作为搜索基因,在特定的搜索域内进行选择、交叉和变异运算,经过若干轮循环,可逼近相关条件下的最危险滑裂面。同时给出实例验算,对该搜索方案进行验证。 According to the geometric statistics and physical and mechanical properties of loess earthquake landslides, a new three-dimensional landslide model is proposed, and the normalized three-dimensional matrix representation is adopted. By borrowing the core idea of ​​genetic algorithm (GA) and taking the third dimension element in the normalized three-dimensional matrix as the search gene, the selection, crossover and mutation operations are performed in a specific search domain. After several rounds of cycles, Dangerous slip surface. At the same time, an example checking is given to verify the search scheme.
