In recent years,with the rapid development of industrial and agricultural production,the combination of sluice and pumping station is often used in some large-scale river construction projects in order to improve the efficiency of water diversion and drainage.Due to the operation conditions of sluices and pumping stations are relatively complex,the interaction between them is also more complex.Therefore,it is particularly important to adopt a reasonable layout scheme.In this paper,the Tonglv Combined Sluice-pump Project was taken as the research object.Firstly,the layout schemes of Tonglv Combined Sluice-pump Project were compared and analyzed.Then,the stress and displacement fields of the main structure of the sluice and pumping station were analyzed by means of three-dimensional finite element analysis software ABAQUS.Finally,the layout scheme of Tonglv Combined Sluice-pump Project was evaluated based on the gray-fuzzy comprehensive evaluation model.The main contents of this paper are as follows:(1)From the aspects of project safety,project management and project investment,the advantages and disadvantages of various schemes for pump station layout,regulating sluice layout and site layout,were analyzed concretely,and the layout scheme was preliminarily selected.(2)The basic principle of finite element method and ABAQUS three-dimensional finite element software were introduced briefly.The ABAQUS software was used to establish the main structure of the sluice station under the layout scheme of pumping station and regulating sluice,and the stress and displacement fields were analyzed.The comparison and analysis of the schemes were carried out to determine the optimal scheme from the point of view of structural safety.(3)The index system for the comparison and selection of the layout schemes of Tonglv Combined Sluice-pump Project was established,and then the indexes were quantified.The weights of each index were obtained by using the subjective methods of non-structural triangular fuzzy method,ring ratio scoring method,and objective methods of exceeding standard multiple method,difference coefficient CRITIC method,and the weights of each index were obtained by using the method based on maximum deviation.The method was used to fuse the weights,and then the weights of each evaluation index were obtained.(4)Based on the grey fuzzy comprehensive evaluation model,the optimum selection and analysis of various schemes for Tonglv Combined Sluice-pump Project were selected to obtain the optimum scheme.
