Analysis on the Mechanism of Difference in Cracking of Super-Long Basement

Abstract

The problem of super-long basement cracking is very common in engineering, and exist obvious differences in various part. Based on the analysis of relevant parameters in the practical calculation formula of temperature stress, this paper analyzed the different cracking mechanism of the baseboard, external walls and baseboard from the qualitative perspective, then explains its inner causes from the aspects of environment conditions, horizontal resistance coefficient and the size effect to help the designer and construction technician to determine the weak lines in anti-cracking and the construction precautions, thereby, improving the qualities of design and construction.
