PRELIMINARY STUDY ON RISK IDENTIFICATION AND CHARACTERISTICS OF LANDSLIDES IN AILAO MOUNTAIN AREA

This article is based on a detailed survey of 1:50000 geological disasters in the Ailaoshan area, Remote sensing data comparison interpretation, Analysis the characteristics of the landslide and explor the risk identification of landslide. Research shows:The pore water pressure was enhanced to form a landslide, and the landslide is a high level bedding landslide; Rock mass of different structure types on the left and right sides of the landslide, and determined the clear boundary shape of the landslide; Rock mass composition structure with steep mid-slope orientation, was the basis for landslide slippage; The occurrence of cracks at the trailing edge of the landslide and the collapse of the soil, It was the initial state before the disaster; Infiltration of heavy rainfall is the trigger condition for the occurrence of this landslide; Insufficient understanding of high(out of vision) disasters and weak sense of risk prevention, It was the disaster condition of this landslide. Analysis of landslide critical disaster risk from risk factors, such as landslide boundary morphology, compositional structure, initial state, triggering conditions and disaster conditions. The identification of landslide risk is only a demonstration in the Ailaoshan area, risk identification similar to landslide needs further exploration, and provide technical support for disaster prevention and mitigation decisions in the region.
