摘要
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。
Safety monitoring is very important for information management of foundation pit,which plays a significant role in ensuring the safety of foundation pit and optimizing the supporting design and construction.In order to feedback monitoring results timely and enhance the efficiency of the information management and data analysis,a safety monitoring information analysis system for deep foundation pit has been developed using Microsoft Visual C＋＋,Microsoft Visual Studio,Net and SQL Server2000.The system was applied in Henglong Plaza,the largest deep foundation pit in Jinan city,to carry out the dynamic management of monitoring information and automatic analysis for monitoring data.Some change laws of groundwater level,foundation pit deformation and internal stress of supporting piles were gotten through such application.The supporting design of foundation pit has also been optimized through real-time monitoring information feedback and analysis.Finally,the safety of pit excavation and the surrounding environment has been guaranteed effectively.
