基坑监测是基坑信息化施工的重要组成部分,对保证基坑安全、优化基坑支护设计和施工具有十分重要的意义。为了及时反馈监测成果,并提高基坑安全监测信息管理与监测数据分析的效率,采用Microsoft Visual C++、Microsoft Visual Studio.Net网络编程技术和SQL Server2000数据库开发技术开发了深基坑安全监测信息分析系统。并将该系统应用于济南市迄今规模最大的恒隆广场深基坑监测分析,实现了监测信息的动态管理和监测数据的自动分析处理,获得了基坑开挖过程中地下水位、基坑变形(桩顶水平位移、沉降、支护桩倾斜)和支护结构内应力的变化规律,通过监测信息和分析成果的及时反馈,优化了工程设计,有效保证了基坑施工开挖和周边环境的安全。
The pit monitoring is an important part of the pit information construction. It is of great significance to ensure the safety of foundation pit and optimize the design and construction of foundation pit support. In order to timely feedback the monitoring results and improve the efficiency of information management and monitoring data analysis of foundation pit safety monitoring, this paper developed a deep foundation pit safety monitoring information analysis system using Microsoft Visual C ++, Microsoft Visual Studio.Net network programming technology and SQL Server 2000 database development technology . The system is applied to the deep foundation pit monitoring and analysis of the largest Hang Lung Plaza so far in Jinan City. The dynamic management of the monitoring information and the automatic analysis and processing of the monitoring data are realized. The groundwater table and pit deformation Pile top horizontal displacement, settlement and supporting pile inclination) and the internal stress of supporting structure. Through the timely feedback of monitoring information and analysis results, the project design is optimized and the excavation and surrounding environment of the foundation pit are effectively ensured .
