摘要

AP1000核电项目中采用有限元分析的方法得到预埋板的承载力

并且在分析中需考虑混凝土对预埋件的影响。本文对混凝土和预埋件之间的相互作用进行研究

基于半空间体在均布压力作用下任意点变形的弹性计算理论

结合美国核安全混凝土设计规范ACI 349锚固计算方法

推导出了预埋板和混凝土两者之间的相互作用关系系数

为AP1000核电项目预埋板有限元分析参数的取值提供了重要的理论依据。

Abstract

Background: The supporting capacity of embedment plates in AP1000 nuclear power plant is obtained by finite analysis method

and the effect of concrete should be taken into consideration.Purpose: The interaction coefficients between embedment and concrete will be studied in this paper.Methods: The theory of elasticity for load distributed over a part of the boundary of a semi-infinite solid and method for anchoring design in nuclear safety concrete structures code ACI 349 are used to proceed with the study.Results: The formulas for interaction coefficients between embedment and concrete were deduced.Conclusions: The study findings can be used for other similar situations and it makes a theoretical foundation for AP1000 nuclear power plant embedment finite element analysis.
