摘要
本文根据上海地区的地震,地质特点,选用岸坡坡度、基岩埋深、岸坡曲率半径、岸坡走向与发震构造走向夹角、顶层粘性土埋深,第一层饱和松散砂埋深及其厚度等七个因素作为工程地质分类因素,根据灰色聚类分析与模糊聚类分析对上海地区发生地震滑坡的可能性作了预测,并用毕肖甫条分法与有限单元法对不稳定地区作了重点验证,在此基础上作成了《上海地震滑坡预测图》。
Taking seven factors into consideration, earthquake landslides in Shanghai are Predicted by grey clustering and fuzzy clustering. Then, instable areas are emphatically verified by Bishop's simplefied solution and finite element method.
