The Studying on the Mechanism of Beiyin Main Channel Gliding SlopeHeilongjiang Beiyin project lies in the west of Heilongjiang which lies the center of Nenjiang .Geographical location is east longitude 124-126?and north latitude 46-48?.Aims of the project are providing water to petrol and chemical industry of Daqing and living water .At the same time it is also a big comprehensive conducting water project without dam which resolves 24 irrigation regions of Beiyin using water along Beiyin. Since 1976 it has been made great achievements which has conducted water more than 100 billion m3 and has been an important project of Heilongjiang province. But recently the channel has been Seriously freezing-melting eroded and sand of cliff edge has been deposited along the channel, which resulted to highten the channel bottom, increase width of the channel and reduce horse road .What all above have affected to apply safely channel so it is necessary to repair comprehensive.The thesis study sliding slope mechanism of high latitude cold region of Beiyin channel, Which is the hope of providing some theory basis about repairing Beiyin project .The thesis mainly study several aspects through geologic dissolve character, climate factors in this region > surface water > groundwater and former provincial edge slope ect. The thesis apply a method of Genetic Algorithm which is combined with Sweden arc method to program to calculate,and regard destroying of Beiyin edge slope during freezing -melting eroding as important destroying factors .Above two points are the emphases and breakout point.Genetic Algorithm which simulates descendiblity and evolution of biologist in nature environment forms a searching method of adapting all-round optimize probability. Genetic has been applied in many fields. The thesis which applied Genetic Algorithm combined with Sweden arc method to analyze edge slope stabilization has made achievements. Comparing former program, it rapids operation rate and makes user interface clearer with VB.6.0.During analysis of former edge slope stabilization, it is not especially that affects of freezing-melting eroding to edge slope to slide .The thesis puts forward Beiyin channel was destroyed by cold freezing eroding, freezing-melting and runoff of melting snow ect.Postgraduate: Sun YingnaSupervisor: Zhang JurongMajor: Water and Soil of Agricultural Engineering...
