A Numerical Analysis of Structural Stress of SinkStyle Road and Influence Factors in the Process of Heat Balance

Abstract

Abstract: Stress distribution condition on the action of heat balance environment of the structure of a certain sink-style road was analyzed by finite element method, which is to get the position and causes of possible failure in the structures of the sink-style road. The impact factors such as thickness and Young’s modulus of the structure anti-floating baseplate, the reinforcement ratio, and positions of reinforcement were also discussed. The results indicate that opening (type I) cracks might be produced firstly at the bottom of the continuous reinforced concrete (CRC) layer. Both the thickness of the structure anti-floating baseplate and the location of the reinforcement pose a notable influence on the generation of type I cracks.

Key words: sinkstyle road, structure antifloating baseplate, stress distributing, finite element method, heat balance
