基于物理力学参数的滑坡灾害监测预警系统研究

Research on monitoring and early-warning system for landslide disaster based on physical and mechanical parameters abstract

针对目前国内采用的预警监测系统现状,展开了云南山滑坡灾害监测预警地高原滑坡灾害研究。以云南省昭通市头寨沟为例进行分析,通过土体粘聚力、内摩擦角、土体位移、孔隙水压力、土壤含水量、土层压力等诱因数据-模拟监测区域降雨-渗流-变形滑动的深度演化模型,剖析滑坡灾害由量变到质变,提出滑坡灾害低成本超前预警理论,实现未来较低成本超前预警,为人民群众及重要基础设施提供生命及财产的安全保障。

According to the current situation of the early-warning and monitoring system adopted in China,the study on landslide disaster in mountainous plateau of Yunnan province was carried out. Through analysis of the causes of the landslide formation in the case of Tuzhaigou in Zhaotong,a city in Yunnan province,this paper analyzes the changes of interior conditions from quantitative change of landslide disaster to qualitative change by means of the data of soil cohesion,internal friction angle,soil displacement,pore water pressure,soil moisture content,soil layer pressure and other causes-the deep evolution model of monitoring regional rainfall-seepage-deformation and sliding,thus proposes a low-cost advanced warning theory for landslide disasters in order to realize advanced warning with low cost in the future and safeguard people’s life and property safety and important infrastructures.
