摘要/Abstract

摘要：

针对山区公路路基边坡点状分布、数量较多、规模相对较小且易受人类活动和环境变化影响的特点，确立了以位移和降雨量为主的监测原则，基于GPRS技术，集成触发式位移计、容栅式雨量计、数据采集传输模块和太阳能供电装置，形成了经济、节能、高效的单体边坡远程监测硬件系统。采用Visual C++网络编程技术，以SQL Server2005为数据库平台，开发了地质灾害远程监测预报软件系统，实现了数据的远程实时接收和可视化分析管理。由于公路边坡变形破坏模式多样，系统还集成了多种时间预测模型，建立了边坡变形预报模型库。通过在常吉高速公路的安装运行，系统成功地进行远程实时监控，保障了极端天气下公路的安全运营。

Abstract:

The slopes of mountainous highways are of such characteristics as dotted distribution, relatively large number but small scale, and easily affected by human activity and environment variation. According to these characteristics, an individual slope monitoring device system is established in this essay. The system mainly aims at displacement and rainfall monitoring, and is developed based on the GPRS technology. By integrating the trigger displacement meter, grid pluviometer, data acquisition and transmission unit, and solar power supply device, the system is proved to be economical, energy-saving and highly efficient. Based on Microsoft Visual C++ network technology and SQL Server 2005 data base，the software system of remote monitoring and forecasting for geological disasters is developed, which realizes the real-time remote receiving and visual management of monitoring data. Due to the variety of slope deformation and failure modes, the system also integrates several time forecast models to establish the slope deformation prediction model database. The monitoring and forecasting system has been successfully applied to Chang-Ji highway, and provided a guarantee for the highway safety in extremely bad weather.

Key words: slope engineering of highway, geological disaster, real-time automatic monitoring, remote monitoring and forecasting system
