山区公路堑坡滑坡灾害实时监控研究

Research on real-time monitoring for landslide disasters at cutting slopes of mountainous highways

我国山区公路堑坡数量众多,其稳定性监控预报研究,对滑坡地质灾害防控具有重要意义。在详细介绍滑坡灾害远程监测系统设计的基础上,依托湖南宁道高速公路堑坡滑坡,建立了以深部位移、渗透压力、裂缝开合度和降雨量为监测单元的单体滑坡监测硬件系统。通过CDMA无线通讯技术,将监测数据实时传输到自主开发的基于SQLite数据库的室内接收分析软件,数据经分析处理后实时发布到互联网。该系统自运行以来,运行稳定,效果甚佳,为山区公路行车安全提供了保障。

There are numerous cutting slopes of mountainous highways in our country. It is meaningful for researching on monitoring and forecasting technology of slope stability to prevent landslide disasters. The design of realtime remote monitoring system for landslide disasters was introduced. An individual slope monitoring device system was established. The system mainly aimed at monitoring on deep displacement, osmotic pressure, crack opening and rainfall. The monitoring data were transferred in real-time through CDMA to the analysis software which was developed based on SQLite database. The data were released to INTERNET after analysis and treatment. The operation status of the system was stable and effective since the running. It provides a guarantee for the traffic safety of mountainous highways.
