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

摘要

在基本农田和自然保护区等三大生态红线受限的情况下，采用沥青混凝土心墙作为防渗来替代粘土心墙的土石坝是水利工程建设的新趋势，也是一种新的创新之路。通过对筑坝材料进行静、动力试验研究，为筑坝材料的力学性能的有限元数值分析提供计算参数。对大坝进行三维有限元静、动力计算分析和研究，为筑坝材料的工程特性、大坝的应力变形特性、稳定性以及抗震安全性和坝体在设计校核工况下的稳定、应力应变特性、坝体结构、筑坝材料参数和控制标准、坝体变形特性、抗震工程设计等方面提出针对性的工程措施。

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.
