摘　　要：为探究结构参数对于基坑变形的影响,以集群南区电力管廊建设项目一标为研究对象,通过调整锚杆长度和锚杆角度对地表沉降变形进行对比分析。研究结果表明:基坑地表变形沉降随着锚杆长度的增加而减小,锚杆角度增加或者减小皆对基坑地表沉降变形产生重要影响,对比得出当锚杆角度为20°时基坑地表沉降变形最小。To explore the impact of structural parameters on the deformation of foundation pits,the first section of the power pipeline gallery construction project in the southern area of the cluster was taken as the research object.A comparative analysis of surface settlement deformation was conducted by adjusting the length and angle of anchor rods.The research results indicate that the deformation and settlement of the foundation pit surface decrease with the increase of anchor rod length,and the increase or decrease of anchor rod angle has a significant impact on the settlement and deformation of the foundation pit surface.By comparison,it is found that the minimum settlement and deformation of the foundation pit surface is achieved when the anchor rod angle is 20°.
