摘　　要：结合具体的工程实例,对深基坑支护方案的选用及设计参数进行了选择,并对土钉支护方案进行了设计和计算,介绍了土钉支护的施工,通过对基坑施工过程中的变形监测,未发现基坑及周围建筑物存在位移及变形超标现象,说明本支护设计是成功的。Combined with one project, the choice of the optimum deep foundation pit supporting plan and design parameter together with the design and calculation of the soil nail supporting plan are made and the construction of soil nail supporting is introduced in this paper. Through the distortion monitoring during the construction of the deep foundation pit, no displacement and the phenomenon of over-distortion is found in the foundation pit and surrounding buildings, which illuminates the success of this supporting design.
