路堑边坡施工期多参数远程监测预警系统应用

摘要

山区高速公路路堑边坡在开挖过程中极可能发生坡体滑动、坍塌,甚至小规模崩塌现象,开发一种路堑边坡施工期多参数远程监测预警系统,保障工程施工期间施工方和当地群众的人身、财产安全显得极为重要.运用多种传感器技术实时地获取施工期间边坡倾斜度、位移和降雨量的变化情况,结合通用分组无线业务(GPRS)和手机短信服务(SMS)技术通过无线方式与上位机进行通信,建立被监测对象各类信息变化的数据库和网络发布平台,同时利用客户端管理软件对危险信息进行预警.通过在毕威高速公路的安装运行,系统成功地在施工期进行了监测预警,避免了不必要的人员伤亡和财产损失.%It is likely to occur slope sliding,caving in,and even small-scale collapse when the mountain highway cut slope in the excavation process. So it is extremely important to develop the multi-parameter remote monitoring and forecasting system for cut slope during the construction period to protect personal and property safety. A variety of sensor technology is used to access the tilt, displacement and rainfall of the slope in construction period, combined with GPRS and SMS technology to communicate with the host computer, and establishs platform of the monitored database and the web publishing. At the same time release the warning dangerous information. The monitoring and forecasting system has been successfully applied to Ri-Wei highway during the construction period, and avoided unnecessary personal and property losses.
