隧道监测信息管理与预警系统的研发及应用

针对隧道施工过程中监测的大量数据难于管理和分析的问题,采用Microsoft Visual C++集成编程环境和SQL Server 2000数据库开发了具有高度实用性、可靠性和扩展性的隧道监测信息管理与预警系统。该系统包含了隧道的勘查、设计和施工的相关资料,重点突出了测点监测数据的存储、处理、查询、分析和预测预警以及报表的自动输出功能。其中预测预警模块以累计位移量、位移速率和位移速率变化趋势作为围岩稳定性的综合判断依据,并根据工程监测经验给出了警戒级别的划分方法,能实时指导隧道工程的施工过程,规避可能存在的风险,保证隧道施工安全可靠。

Development of Monitoring Information Management and Early Warning System for Tunnel

In view of difficult management and analysis of mass monitoring data about constructing tunnel, by using Microsoft Visual C++ technology and SQL Server 2000 database, the authors develop a tunnel monitoring information management and early warning system, which has the advantages of practicability, reliability and extensibility. The system includes tunnel information related to its geology, design and construction, emphasizes the functions of information treating such as storage, process, query, analysis, prediction and early warning and automatic output of monitoring reports. The early warning module uses cumulative displacement, displacement rate and the trend of displacement rate as the criterion of surrounding rock stability. It can be used to guide the tunnel construction in real time, which plays an important role in evading possible existed risk and ensures the construction safety and reliability of tunnel.
