Abstract

Abstract

Conservation methods and technical indicators of mass concrete construction are often selected based on engineering experience,combined with on-site curing according to temperature monitoring,which lacks theoretical foundation,and inappropriate conservation methods and technical indexes will lead to further escalation of construction cracks.In this paper,taking the base of a CPR1000 nuclear power plant for example,through various curing methods and technical indexes,the stress state of concrete is analyzed by finite element method,thereby optimizing the curing methods and technical indexes and then to guide the selection of curing measures.Theoretical analysis results show that the dynamic differentiated technical measures are more conducive to the quality of concrete.All these can provide experience accumulation and theoretical support for curing similar foundations.
