Abstract

There is an inestimable role in a reasonable sliding layer for reducing cracks in mass concrete construction.Actually,many factors have an impact on cracks in concrete construction,but the fundamental and direct causes are temperature stress level and anti-crack measures.There are also many factors to generate different stress level,such as the size and the form of poured concrete foundation,hydration heat and rate of cementitious materials,curing measures,as well as the sliding ability of the sliding layer and so on.In this paper,the finite element models of the sliding layer and the overall structure are built,finite element analysis of temperature stress on upper structure with a sliding layer and strain-monitoring are carried out.The results from the theoretical analysis show that the sliding ability has a direct impact on the level of temperature stress,at the same time,according to results of the test and theoretical analysis,this paper has given quantitative models of the sliding characteristics,which provides practical methods and experience for the theoretical analysis for the batch CPR1000 nuclear power project or similar projects.
