3-D FEM Analysis On The Culvert Of The High Dam

Culvert is the structure of water'stransport that burying below the filling, the burying culvert that pressed by dam be provided with the shronrpoint that little dig capacity,simple construction,short time limit for a project and province investment and so on, therefore it is applied abroad by the project of reservoir and electricity. But the phenomenon that the culvert is destroyed by improper design and construction occurs occasionally, some culvert is push down and destroy for the soil press is not take into account plenty that lead to the madequate intensity of culvert . By licale investigate on operate there are 63. 5% culvert appears crack, there are 70% is portrait crack ; In addition,some culvert has not been used in gear for the excessive sedimentation by unequal portrait. For the sake of the safe employ of the configuration of the culvert ,confirm the soil press nicetily and control culvert's unequal portrait settlement is the key point in project practice.This article adopt three-preserve ball-model finity formality ,simulate the construction process of culvert's delaminate stuff, analysis the upright sort pressuess of culvert and the circumambience of dam and the movement of vertical displacement in contruction process, present out the and displacecement of culvert and the circumference of dam at a period of completement and sluice . Analysis the construction of delaminates filling of ascending soil by finity method. It is not only reflect the common disciplinarian in receiving force and transfiyurarian in receiving force and transfiguration of filling at more pressness, but also estimate the reciprocity connection such method that simulation by way of make groundwork ,culvert and soil substame as one unify integer . And consider resiving the effect mechanism of the measure in decrease pressness. It investigates the infection that the filling thickness of the material in decreasing pressness operates the soil pressness and displacement of culvert by calculating and analyzing three filling thickness of minus material. At last it analysises the influence that asymmetry sedimentation and the soil pressness of the peak of culvert for different cavity group depth..
