以常州市某不规则设备基坑工程为背景，针对由自然放坡、土钉墙、钻孔灌注桩加锚杆组成的复合支护，采用多种参数验算分析了地面重型吊车动超载对基坑的稳定性影响，结果表明地面动超载对基坑的位移及抗倾覆系数影响显著。%Taking the irregular equipment foundation pit project in Changzhou as the background, the study adopts parameter calculus to analyzes the influence of the ground heavy crane ＇ s moving overloading on the stability of the foundation pit according to the composite support with the nat- ural sloping, the soil nailing wall, the bored pile with anchor, and proves by the result that the influence of the ground moving overloading on the displacement of foundation pit and the overturning coefficients is obvious.
