某高层建筑地基的边坡稳定分析

Slope stability analysis of ground soils of highrise building

以某建造于高边坡上的高层建筑为背景,重点分析了自然边坡的整体稳定性以及地下室、桩和地下水等多种因素对边坡整体稳定性的影响,并计算得到了各种情况下边坡的安全系数和最危险滑动面。分析发现,地下室的外墙抗剪和桩的抗滑对边坡稳定具有一定的提高作用,而地下水的浮力和对土性指标降低共同作用使得边坡稳定性有所降低性。考虑上述各因素的影响,结合本工程给出了评估该类高边坡地基稳定性的方法以及增强其稳定性的设计措施。

Based on the building constructed on a high slope,some factors which influence the slope stability are analyzed,such as basement,piles and underwater.Then,safety factors and most dangerous slide surfaces of each condition are obtained.It is found that the slope stability is strengthened by the outside wall of basement and piles,while the slope stability is reduced by the underwater.Considering such factors and the current project,the method of evaluating high slope stability is proposed,and design measures are also proposed to strengthen the slope stability.
