摘　　要：为提高城市深基坑及周边建(构)筑物安全监测效率,以智能全站仪为基础,结合城市深基坑安全监测需求,设计开发了全站仪自动化监测系统。通过设计监测系统框架结构,明确系统主要功能及核心构成;依据监测规范设计系统业务流程,并采用基准网检校和气象环境补偿算法对观测数据进行平差处理,提高数据质量。同时利用某地铁车站深基坑监测项目对监测系统应用效果进行分析研究,采用人工监测方法对不同施工节点监测点变形数据进行复核,与监测系统数据成果进行对比,验证了监测系统数据成果的可靠性,与人工复核结果和施工节点理论变形特征基本一致,能够为基坑工程安全施工提供准确可靠的高频高精度变形监测数据,保障基坑主体及周边建(构)筑物安全。In order to improve the safety monitoring efficiency of urban deep foundation pit and its surrounding buildings,based on intelligent total station and combined with the safety monitoring requirements of urban deep foundation pit,a total station automatic monitoring system was designed and developed.Through the frame structure design of monitoring system,the main functions and core composition of the system were clarified.The business flow of the system was designed according to the monitoring standard,and the adjustment processing of the observed data was carried out by using the algorithm of benchmark network check and meteorological environment compensation to improve the data quality.At the same time,the deep foundation pit monitoring project of a subway station was used to analyze and study the application effect of the monitoring system.The deformation data of monitoring points at different construction nodes were reviewed by manual monitoring method,and the results were compared with the monitoring system data,which verified the reliability of the monitoring system data results and basically consistent with the manual review results and the theoretical deformation characteristics of construction nodes.It can provide accurate and reliable high-frequency and high-precision deformation monitoring data for the safe construction of foundation pit engineering,and ensure the safety of the main structure of pit and its surrounding buildings.
