Research On The Simulation Model And Stress-strain Of RCC Dam

Roller compacted concrete dam is a new type of dam rolling equipment and technology applied to the construction of concrete dam,RCC dam construction process is simple,small amount of cementitious materials and template,TLC large placement of rolling reduction parting,conducive to the sustainable construction,streamline the temperature control measures,so as to speed up the pace of construction shorten the construction period,reduce the cost of the project.Considering the cost of seepage control facilities,the cost of RCC dam is still higher than that of normal concrete dam.This paper describes the method of dam structure analysis,introduces the development history and the basic principle of finite element,and the concrete dam material constitutive model analysis,calculation and comparison of selected suitable for this constitutive model.In this paper,a three dimensional model of the complex gravity dam is established by using the finite element analysis program,which is based on the RCC dam in Jiangxi.The stress distribution of dam and dam foundation is revealed,and the integrity of dam body is evaluated scientifically.In this paper,and a Jiangxi water conservancy hub combined with the RCC dam as the research object,using ADINA software to establish the 3D mesh model,analysis of roller compacted concrete dam under various conditions of stress and deformation of the dam are calculated and simulated to calculate the deformation of normal water stress,design flood level and check flood the dam and its foundation.It is concluded that the RCC gravity dam is safe.In the numerical simulation of this time,obviously reflect the dam stress distribution,not only the important technical basis for engineering design and construction,but also provide a useful reference for similar engineering construction.
