| 摘 要： | 通过野外地质调查和钻孔以及物探资料,分析了大华桥斜坡体的成因机理,并提出了斜坡变形的地质力学模式。初步认定大华桥斜坡体是一个塌落堆积体,以错落为主。大华桥斜坡的形成过程主要分为两个阶段:(1)堆积体的形成;(2)斜坡体的形成。目前斜坡体尚未形成贯通的控制性软弱界面,斜坡整体处于稳定状态。

| Abstract: | Based on a great deal of field investigation, bore drilling and physical exploration, formation mechanism of Dahuaqiao slope is analyzed and a geo-mechanical mode is proposed to explore the slope deformation. The results indicate that the slope body is originated from collapse deposit which is caused by deferential settlement. The formation of Dahuaqiao slope is divided into two stages: the formation of deposit, and formation of slope body. Now weak slide surface the slope does not go through the whole slope body, and the slope is in good stability condition. |
