摘　　要：文章介绍一种公路滑坡监测系统在四川省内-宜高速公路的高填方、高边坡路段中的应用。介绍了直射式大气激光定位二维地表变形测量新方法及以5种监测方法为基础建立起来一种立体、全面、实用和富有新颖性的监测系统。该系统经3a现场监测实践,不但确认了监测地段滑坡稳定性,而且以小的监测投入节约较大工程投入,取得了显著的社会经济效益。This paper introduces the application of a landslide monitoring system on the high filled ground and the high-slope of Nei-Yi expressway.The two-dimensional laser displacement monitoring technique and the monitoring system which consists of five monitoring methods are introduced.The system is a three-dimensional,comprehensive,practical and novel monitoring system.The landslide stability was validated after monitoring for three years and the engineering investment was avoided.The social and economic effect are very well.
