Research Of Chongzhui Accumulation Body’s Cause Of Formation In Basin Jilong Tibet

Jilong port in Tibet autonomous region is a very important landway frontier ports,in the economic development of Tibet in different historical periods have played avery important role. Survey and evaluation of area is located southwest of TibetanPlateau, on the south slope of Himalaya Range die La mountain hill between bagatelleand ancient hill, for the alpine valleys. Overall, the North West, South East High low,the highest point is located on the north side of the mountain in NaiXiavillage,elevation of3900m. Lowest point on the Jibu village south of JILong zangbo,elevation of2400m, relative altitude1500m. JiLong port land area of about0.16km~2status, of about thousand resident population. Port Road, north through the townshipin JiLong.The border of JiLong port are162km long.22.778km away from the townof JiLong hot rope bridge is at the Sino-Nepalese Highway intercourse and boundaries.Suspension Bridge to Nepal from the heat and85km of Kathmandu.ChongZhui accumulation in the work area east of the ChongZhui village, Northslopes of the granite bedrock, River JiLong zangbo south of the accumulation.Accumulation of body distribution of a large block of granite blocks several metersdiameter, accumulation body has three unstable rock slope north of collapse, RiverJiLong zangbo with a bank collapse is also on the accumulation. accumulation in thebody of the east also a large number of ground subsidence. Accumulation and stabilityof the causes of the early research on port construction work has important researchsignificance. In this paper, the hydraulic part of the region to collect comprehensive data onthe basis of exploration, analysis of the causes of Chongzhui accumulation, specialanalysis of the collapse pit during the causes of formation. Formation through theaccumulation of surface water after the impact of the transformation of the river, cometo the reasons for the formation and collapse pits to restore its formation process. Thisarticle also within the region of collapse, bank collapse and ground subsidence riskassessment. The mechanism of ground subsidence analysis and numerical simulation,come to will there ground subsidence conclusion. This article attempts to accumulatethe body of the groundwater seepage study of stability of the ground, Role in definingthe potential erosion of a new type, reference for the later similar research questions.
