重力式挡土墙抗滑动稳定计算方法改进研究
摘要:针对目前重力式挡土墙抗滑稳定性计算方法中存在的缺陷,将挡土墙入土部分划分成小网格,遍历搜寻出抗倾覆稳定系数最小的点,此点就是挡土墙的实际倾覆转动点所在的位置,根据此转动点的位置,将挡墙两侧的土体划分成四个部分分别计算各部分土压力,再结合墙底与地基土摩擦力的分析,推导出改进的墙体抗滑动稳定系数的计算公式。还通过改变墙体的几何参数,分析了最小抗倾覆转动点的位置和墙体抗滑稳定性系数随墙体宽度、挡土墙入土深度等的变化规律。
Abstract:The present anti-sliding stability calculations of gravity retaining wall has some defects. This paper had divided the retaining walls that buried into earth in small grid. By searching for the point of minimum stability factor against overturning. This point is the actual turning point of the retaining walls. According to the location of this turning point, both sides of the wall are divided into four sections in order to calculated the earth pressure. At the end of the analysis, combining the friction of soil and foundation wall to get the improved anti-sliding stability factor formula. This article also, analysised the location of the minimum turning point of overturning and the anti-sliding coefficient of stability, and how they change with the change of retaining walls, width and depth that buried into earth.
