Mountain Highway Landslide

Highway landslide is a serious problem of highway communication and transportation in mountain area. Among disasters causing the loss to highway, landslide has been one of the most serious disasters. Highway landslide is defined as a series of landslides affecting common operation of highway along the highway line under the comprehensive effect of the climate, hydrology, geological environment and mankind activity. In China, disaster of highway slolpe is very serious. It has caused tremendous economical loss. The thesis combines with landslides along the Yuan-Mo Highway line, on the basis of obtaining project geological data and harnessing measure of enormous landslide, and sees through many sides of highway landslide by summation, contrast, statistics and analysis.Firstly, the thesis analyses the relation between highway landslide and developing environment, including relations with geomorphology of landslide growing region, geological structure, layer lithology, hydrological geology, earthquake, atmosphere precipitation, sueface vegetation and mankind activity. The author thought that 8 elements have effected the landslides along the highway line in combination with Yuan-Mo Highway open to traffic, and thought that the distribution of mountain highway landslide has close relation to developing environment.Secondly, the author put forward the method of calculating stability of highway landslide through fuzzy theory in view of intentive, complication of calculating stability of landslide distribution. This method has lots of merits, such as not having to find out sliding surface of landslide, easily gaining evaluating parametes, and good effect of regional landslide stability. At the same time, it also has some faults, such as experience and obscurity.Then, the author combines with relatively typical harnessing programme along the Yuan-Mo Highway line by means of statistical analysis in mathematics, and gain the following questions. Highway landslide lay controlling project and restraining project on the place of equal importance. Most landslides have close relation to rainfall and need to adopt cut-off mersure. Ecological landscape and safety are both specially attentive problems ofmountain higway, and so on.Finally, in order to successfully apply harnessed landslide to preparatory one, the thesis gives raises to highway landslide harnessing programme dicision model of model reasoning. The model makes designer to quickly find out harnessing process of similar landslides.
