广安市某住宅小区高边坡特征及稳定性分析

Characteristics and Stability of High Slope in a Residential District in Guang'an

在广安市某住宅小区土石边坡勘查成果基础上,对边坡的特征、形成机制以及稳定性进行了评价。结果表明:该边坡地质条件简单,在天然工况下处于稳定状态,在强降雨或持续降雨等不利条件作用下处于欠稳定状态,暴雨工况下易失稳。建议对边坡部分采用抗滑桩或护坡墙方案进行支护,坡顶结合做好截排水工程。

This paper deals with characteristics,genetic mechanism and stability of high slope in a residential district in Guang'an.The slope is an earth-rock slope.It has simple geological condition without fault.It is stable in natural state and unstable underheavy or sustained rainfall and other adverse condition.It is suggested that anti-slide pile or pile-wall combination scheme should be adopted for the backfill slope,protecting wall or bolting and shotcrete method should be used to excavate the exposed part of bedrock andthe top of slope should be combined to do a good job in intercepting and draining water.
