Analysis of the Stability Calculation of Gravity Cement-Soil Wall with Backfill Reinforcement in the Pit
摘要
Abstract
This paper discusses the stability calculation of gravity cement-soil wall with backfill reinforcement.The variation patterns of overall stability,anti sliding stability,and anti overturning stability under different wall widths and embedded depths were analyzed through examples.The variation patterns indicate that:the sensitivity of the overall stability safety factor to wall width is not very high;when the embedded depth exceeds a certain depth,increasing the width of the cement soil wall does not significantly increase the safety factors for anti sliding and anti overturning stability for the same embedded depth.Based on this law,a simplified method for calculating the stability of gravity cement soil walls with pit reinforcement is proposed,which can be divided into two steps.Firstly,the gravity cement soil wall(without considering the length of the cement soil wall under pit reinforcement,i.e.taking the same depth as the pit reinforcement)and the pit reinforcement are used as a whole to calculate the anti overturning stability and anti sliding stability of the structure.Secondly,only the gravity cement soil wall is considered to calculate the overall stability and anti uplift stability.Finally,the feasibility and reliability of this simplification are verified through engineering example.关键词
