Design Of Monitoring System For Sliding Slope Body In Special Environment Of Tibet Plateau

China has a vast territory,with mountains(including plateaus and hills)covering more than 6.6 million square kilometers,accounting for 69% of the total land area,The population of mountain area accounts for more than 30% of the total population of the country,and the area of mountain area accounts for a large proportion,with the increase of natural disasters.In recent years,frequent natural disasters such as debris flow,landslides and rolling stones have brought huge losses to the country.Tibet is an important strategic area and ecological barrier in China.The Sichuan Tibet highway is an important material support channel and an important infrastructure for the mainland and Tibet.At the same time,Sichuan Tibet highway is also an area with frequent geological disasters.The disaster monitoring system studied in this paper is built in Bomi section of Sichuan Tibet highway.The specific contents of this paper are as follows;(1)Based on the field investigation and data collection,the traffic,hydrological,geological and meteorological conditions of Dazi area and the area where the debris flow gully is used as the monitoring point are described.When the monitoring point of Da zi landslide is established,the high-density electrical method is used to analyze the slip surface of the landslide,It can be used for reference in the future.(2)Based on the theoretical basis of monitoring data and early data in the preliminary monitoring system,it is concluded that the landslide in Dazi county is in an unstable state;It is known that the Tianmogou monitoring point system is running normally at this stage through preliminary debugging and understanding of the platform.(3)In the future,in the establishment of high altitude landslide monitoring system in Tibet,the service life of the corresponding monitoring equipment is much shorter than that in the mainland due to the relatively high altitude and strong sunlight ultraviolet radiation,so the equipment with relatively low cost should be considered.(4)In the establishment of Tianmogou monitoring point,through the design of the monitoring system and the study of the performance of monitoring equipment,a binocular monitoring scheme based on machine vision is designed as an attempt.It is expected to verify the accuracy of machine vision by comparing the two.
