摘要
基于Melan解得出了临近开挖对既有挡土墙整体稳定性影响的计算公式,并分析了开挖距离和开挖深度对抗滑移和抗倾覆安全系数的影响,分析计算结果与实际案例中的结果吻合.
Based on Melan solution, the calculation formula for the effects of excavation at the bottom of the wall on the existing retaining wall stability was obtained. And the effects of the excavation distance and excavation depth on the anti-sliding safety factor and anti-overturning safety factor were analyzed. The calculated data were in agreement with the results of the actual cases.
