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。Background： The supporting capacity of embedment plates in AP 1000 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 embedrnent 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.
