Super highway as an important part of national infrastructure brings hidden troubles about mass sloping excavation that would cause unstable disaster during the continuously exploitation especially in mountainous area.Thus we focus on unstable factors in mountainous highway excavation and give priority to deformation monitoring and induction monitoring as main developing work putting forward an integrated monitoring and warning system including the Sensor Networks,Transmission network,Data Management,warning at the scene and SMS warning.It works as a technical backup to sloping excavation monitoring and warning system during construction period.This system is applied to the high way from Bijie to Weining in Guizhou province effectively.%高速公路作为国家基础建设的重要组成部分,随着开发力度的不断加大,特别是山区高速公路的建设,形成了大量开挖边坡失稳灾害隐患。为此,重点研究了山区高速公路开挖边坡失稳因素,提出了以变形监测、诱发因素监测为主的系统研制工作,形成了传感网、传输网、数据管理、现场报警、短信息报警于一体的监测预警系统,对于高速公路施工期边坡监测预警能够起到较好的技术支撑作用。该系统已经在贵州省毕节至威宁高速公路部分标段进行了工程应用,效果良好。
