Evaluating Of Stability And Study On Treatment Engineering For A Landslide In The Yangtse River Three Gorges Reservoir Area

The Yangtse River three gorges is dangerous and difficulty narrow pass since ancient times, Have another the mountainous country,the mound area of the typical model, reservoir in Yangtse gorges became the dry subsidiary current database shore of more than 5300 kilometerses after retain water, the water level soar, the water pressure enlarge.Database area add the special geography condition,complicated geology environment and many rain subtropics the monsoon weather etc. for the geology disaster of growth provided an extremely beneficial condition, the engineering construction activity inside the area is gradually multifarious, the influence of these mankind's activities, cause a slippery ascent,mudslide of that area etc. the mountainous country ground the disaster is a more multifarious occurrence.Give the movement of engineering in Yangtse gorges,immigrate to move to construct huge obstacle, constituted serious threat to database area in Yangtse gorges people's life property safety in the meantime.In this paper, a systematic study is carried out on the harness engineering of landslide in the Yangtse River three gorges reservoir area,which includes the evaluation of hazard,the stability nanlysis and the supporting system of landslide,the monitoring system and the project design.through these studies and analysiss,following conclusions could be drawn:(1)The landslide is chiefly controled by rock characteristic and such compose feature, rock discontinuity structural plane, Groundwater , human engineering effects, Else effect like earthquake and so on element is relatively slight.(2)The landslide body has obvious initiative segment and passive segment.. 130m altitude upwards is initiative segment,130m-91m is passive segment.(3)The surplus fall dint curve displays the slippery ascent body change type to start a mechanism.The department(active segment) brushes a square to reduce to carry after the slippery ascent body win,, reducing the fall dint, and slipping to construct a thing in the ascent feet constitution, and carry in the ascent body ex- good luck heap, increase slippery dint of its anti-, carry on protecting an ascent to the ascent noodles, is extremely beneficial to the whole stability.(4)The slippery ascent is a whole and basic stability under the natural appearance.Its minimum and safe coefficient is 1.15.The slippery ascent mainly expresses for the ascent before the body the good luck all levels the part of the abrupt...
