摘　　要：为了检测土钉支护技术在郑州等地区深基坑工程中的适用性和可行性,对某基坑开挖过程中基坑周边的安全情况进行了跟踪监测。采用精密水准仪和测斜仪对基坑西侧和南侧的两条主干道路、基坑在开挖施工中向坑内的水平位移及基坑周边主要建筑物的沉降进行了观测。监测结果表明,各测点沉降位移和水平位移均满足工程要求,土钉支护取得了明显的预期效果。The soil nailing support techniques have been widely used in the deep foundation pit with many advantages such as simple construction machine,economical investment,lightweight construct,fast construction progress.The soil nailing application in a deep foundation pit in Zhengzhou has been analyzed and the settlement of the surrounding road and architecture and the horizon displacement of the pit side was monitored. Results indicate the settlement and the displacement can met the engineering request. The soil nailing support got the expected effect.
