Study On Structure Calculation And Security State Analysis Of Simaoyou Sluice

From ancient times to the present,people focus sustained attention to Water conservancy project.the sluice is an important part of the hydraulic Engineering,which undertake major tasks that are the flood control,irrigation,water supply and so on.besides, the sluice plays an important role in protectting the vital interests of the people and the sustainable development of economy and society.In the light of the Simaoyou sluice in Jiangsu Provincet,the chamber structure of Simaoyou sluice is calculated and analyzed, and the fuzzy comprehensive evaluation model is established to analyze the Simaoyou sluice safety state.The main contents are presented as follows:(1)According to the structure characteristic of anti arched floor.The structure strees of Simaoyou sluice anti arched floor is analyzed by the control point coordinate method and arch moment distibution method two calculation method,then compare the results analysis.(2)The principle of finite element analysis method is described and the three-dimensional finite element software ABAQUS basic theory is described.Through ABAQUS,the Simaoyou sluice anti arched floor model is established to analyze the internal force,and then The results of the finite element calculation are compared with the control point coordinate method and arch moment distibution method.(3)The stability of the Simaoyou sluice chamber is analyzed and UsingThree dimensional finite element ABAQUS software analyze the Simaoyou sluice structure and make Field research on the stress analysis of main components of the Simaoyou sluice.(4) Based on the provisions of the safety appraisal, The project safety state evaluation index system of the Simaoyou sluice is built, According to "the analytic hirearchy process "and "entropy" two kinds of subjective and objective weighting method of combination weighting method,fuzzy comprehensive safety evaluation model is setted to judge the safety state of Simaoyou sluice.
