Design Optimization And Construction Simulation Of Concrete Gravity Dam

As one of the widely used dam types,the structural safety of concrete gravity dam has always been a very important issue in design and engineering,and the variation law of stress-strain behavior of dam body has always been an important evaluation index of structural safety of gravity dam.Due to the large section size of gravity dam,the safety is high.However,due to the large section size,the strength of materials inside the dam body can not be fully exerted,and concrete materials are wasted.At the same time,reducing the section size can simplify the temperature control measures during construction.Therefore,it is necessary to design a reasonable section size of gravity dam,and the structure of dam body should be added according to the actual situation in the design of gravity dam The structure optimization design.Based on the traditional two-dimensional drawings are not intuitive enough for construction design,it is meaningful to study how to display the construction design drawings in a visual and dynamic way.In this paper,a concrete gravity dam under construction in a certain place is taken as the research object.On the basis of the known original data,according to the actual situation of the concrete gravity dam,based on the large-scale finite element software ABAQUS,the three-dimensional finite element model of the concrete gravity dam is established for static and dynamic analysis,so as to verify the feasibility of the dam structure design;on the basis of structural analysis,the dam section is analyzed The main research work is as follows:(1)A typical gravity dam section is selected for static analysis to study the displacement and stress distribution of the gravity dam under different static load conditions,and the safety of the normal operation of the dam is obtained.(2)Based on the static analysis,the seismic dynamic response of the gravity dam is studied,and the seismic safety performance of the dam is obtained.(3)MATLAB and ABAQUS tools are used to write the genetic algorithm optimization program This method overcomes the shortcomings of the existing optimization methods.Through the MATLAB programming language to write the corresponding command,directly call ABAQUS software to carry out the finite element calculation in the background.The fully automated joint program improves the optimization speed.Combined with the advantages of finite element method and intelligent algorithm,the best optimization scheme meeting the conditions is designed.(4)Based on BIM related software tools,the reasonable design results are visually displayed and simulated.The 3D gravity dam model is established by using related software tools.Combined with the prepared gravity dam schedule,the implementationof bim-4d model is studied.The process of dam construction pouring is reproduced,and the visual dynamic construction schedule management is realized to guide the construction.Compared with the traditional schedule management method,it fully shows the advantages of introducing BIM Technology,and reflects the practical application of BIM Technology in water conservancy construction design.
