Geological Hazards And Their Distribution Characteristics In Tianshan Road And Countermeasures

Since twenty centuries 90's, unceasingly have enlarged along with the country to the transportation infrastructure investment dynamics, newly built, rebuild mountainous area road more and more many, rank also more and more high, the mountainous area highway design, constructs the technical level also to obtain the enormous enhancement, the new theory, the new method, the new technology, the new material which the mountainous area road disaster prevents and controls has unceasingly emerged, but these achievements and the level all obtain based on the general mountainous area, to high and cold, the high elevation, the crag body gale, the vegetation scarce, the rainstorm, the storm snow frequent mountainous area road disaster studies then are less.This article in the scene investigation and study and in the acquisition of information foundation, has along the route done the system research to the Tianshan road geology disaster. Its main content includes: (1) Through to studies the area the physical geography and the engineering geology environmental condition analysis, summaries the road along the route geology disaster time, the spatial distribution rule and the main characteristic. (2) In detail elaborated the avalanche, the landslide, the mud-rock flow growth distribution characteristic, the origin condition and the influence factor; Has established the basic pattern and which in the research area the avalanche destroys has carried on the value simulation using a separate Yuan method to the model avalanche; Has analyzed the typical landslide basic characteristic and the destruction development, and has appraised its stability through the quantitative evaluation; Through the different classified standard, proposed the road along the route mud-rock flow classified plan, has analyzed the typical mud-rock flow origin mechanism; Put forward the corresponding preventing and controlling proposal to each kind of typical disaster. (3) Utilized the fuzzy synthesis judgment the method to study in the area the geological disaster risk to carry on the quantitative evaluation and to carry on the comprehensive district appraisal. (4) Had pointed proposed the preventing and controlling countermeasure to the road along the route geology disaster.
