摘　　要：深基坑监测是保障开挖施工安全的一项重要工作。文中针对常规方法复测工作量大,对环境要求高等问题,提出了一种深基坑水平位移监测新方法:以边角交会建立平面控制网,结合全站仪自由设站方法。理论分析和实例结果表明,新方法内外业工作效率更高,对于深基坑监测具有重要实用价值。Deep foundation pit monitoring was a key issue to ensure the safety of excavation construction.In view of the heavy workload and the high environmental requirements of the conventional method,a new method of horizontal displacement monitoring of deep foundation pit was proposed in this paper:the plane control network was established by the intersection of edges and corners combining with the method of free station setting by total station.Theoretical analysis and case study results showed that the new method was more efficient in the field and had important practical value for deep foundation pit monitoring.
