Application and practice of three-dimensional finite element stress variation and static calculation in Reshuihe Reservoir

Abstract

In cases where the three major ecological red lines such as basic farmland and nature reserves are restricted, the use of asphalt concrete core walls as anti-seepage measures to replace clay core walls in earth-rock DAMS is a new trend in water conservancy engineering construction and also a new innovative path. Through the static and dynamic test research on dam-building materials, the calculation parameters are provided for the finite element numerical analysis of the mechanical properties of dam-building materials. Three-dimensional finite element static and dynamic calculation, analysis and research on the dam are carried out, and targeted engineering measures are proposed for the engineering characteristics of dam construction materials, the stress and deformation characteristics, stability and seismic safety of the dam, the stability of the dam body under design verification conditions, stress and strain characteristics, dam body structure, parameters and control standards of dam construction materials, deformation characteristics of the dam body, and seismic engineering design.
