Research On Design Optimization Of Hydraulic Flood Discharge Tunnel Based On BIM Technology

With the continuous development of computer technology,earth-shaking changes have taken place in various fields of engineering construction.From hand-drawn drawings to CAD software drawings,the first " drawing board rejection" revolution in the construction industry was realized.Now,with the continuous development of various fields of engineering,the competition within the industry is increasingly fierce,and the facade forms of buildings are also different in shape.At the same time,the information of each participant in the engineering project is independent of each other.Engineering changes are even more common in the process of engineering construction.Traditional design methods can no longer meet the needs of the current development of various fields of engineering.The birth of BIM technology has brought new design concepts to engineering construction.The BIM technology is based on information data in the construction phase of an engineering project and uses digital methods to simulate real buildings to express the physical and functional characteristics of buildings.At present,traditional CAD drawing is still the preferred method for major design institutes to carry out engineering design.However,with the continuous promotion of BIM technology,it has been widely promoted and applied in construction,mechanical and electrical,municipal and other professional fields.BIM technology has also been studied and applied in various aspects of hydraulic engineering specialty to varying degrees,but it is still in the initial exploration stage.This paper mainly studies the application of BIM technology in hydraulic flood discharge tunnel design optimization through the following four parts:(1)This paper discusses the concept,technical standard and research of BIM technology at home and abroad by consulting relevant literature and materials.(2)This paper expounds the engineering design process of the core Building Information Modeling software Revit.Taking the circular hydraulic tunnel as an example,the establishment of three-dimensional parametric simulation model of flood-discharging tunnel using Revit is described in detail,and the engineering drawing is realized by using the established parameterized simulation modeling.Preliminary discussion on Parametric Modeling Design method of hydraulic drainage Tunnel based on BIM Technology Core Modeling Software Revit.(3)This paper introduces the calculation method of hydraulic tunnel structure and the method of determining the load.Taking circular hydraulic flood discharge as an example,the structural analysis and calculation method of Revit hydraulic flood drainage tunnel structure model based on finite element is preliminarily discussed,and some pressureless It is applied in the scheme design of the horizontal layout of hydraulic discharge,and it is proposed to adopt the horseshoe shape in the cross section of the pressureless flood discharge tunnel under the condition of meeting flood safety.(4)Taking the flood discharge tunnel project of the Shuixi River Bridge of Chengkai Expressway as an example,using Revit to establish a parametric model,the necessary route plan for the flood discharge tunnel,the overall layout of the project,the design of the cross section,and the structural mechanics analysis and reinforcement are completed.Calculate,and draw the map in the plane and elevation of the project.Finally,based on Revit,the 3D simulation model of the entire project was established and compared with the actual engineering results.This paper preliminarily explores the design method of hydraulic flood drainage tunnel model based on BIM technology,and takes the Shuixi River flood drainage tunnel project as an example.Based on BIM technology,the simulation model of flood drainage tunnel is used to realize the design of hydraulic flood drainage tunnel model.The parametric model design of hydraulic drainage tunnel provides certain reference.
