盾构施工地表沉降自动化监测及数据移动发布系统

地表沉降监测是盾构信息化施工的重要组成部分，对优化盾构施工参数，保证施工安全具有十分重要的意义。为了及时共享和反馈监测成果，提高监测信息管理与数据分析的效率，采用Microsoft Visual Studio .Net编程技术和MySQL数据库开发了沉降自动化监测及数据移动发布系统，实现了24 h监测数据的自动化采集、分析和移动端推送，并将该系统应用于南宁轨道交通1号线盾构隧道下穿南宁火车站铁路股道及站房工程，获得盾构推进过程中的地表沉降及火车轨道沉降的变化规律。通过监测数据和分析成果的及时反馈，优化了盾构机施工参数，有效保证了盾构掘进和周边环境的安全。

Automatic monitoring and mobile data publishing system of ground settlement induced by shield tunneling

Ground settlement monitoring is an important component of shield informatization construction, and it has a very important significance in optimization of shield tunneling parameters and safety of construction. In order to share and feedback monitoring results timely, improve efficiency of monitoring information management and data analysis, an automatic monitoring and mobile data publishing system of ground settlement is developed by using Microsoft Visual Studio. Net programming technology and MySQL database to realize 24 hour automatic acquiring, analysis and mobile publishing of monitoring data. And then the system is applied to the project of shield tunneling of Nanning Metro Line 1 traversing below tracks and buildings of Nanning Railway Station; the variation law of ground and track settlement caused by shield tunneling has been obtained. By the in-time feedback of monitoring data and analysis results, the construction parameters of shield machine is optimized so as to effectively ensure safety of shield tunneling and surrounding environment.
