Analysis Of Temperature Stress In Super-Length Concrete Structure With The Pile Foundation

With more and more super-length concrete structure buildings with the pile foundation have been constructed, the temperature stress of super-length concrete structure has become one of vitally important research topics in structure design This paper elaborates the reason of cracking, and the related theory of pile lateral direction stiffness. Then, using finite element analysis method, this paper carried on quantitative analysis. This paper main achievement includes following several sides:1. Analyzing the reason and the influence factors of temperature cracking of the super-length concrete structure, this paper advances the common preventing and controlling measures. According to the weather of zhejiang, this paper produces the seasonal temperature difference value which is needed by super-length concrete structure designing;2. Analyzing lateral direction stiffness of the pile, this paper produces the calculating formula.3. Analyzing influence lateral direction stiffness of pile to temperature stress of super-length concrete structure, this paper proposes the method, named "law of regulation of lateral direction stiffness" , which controls temperature stress of super-length concrete structure through control lateral direction stiffness of pile. After further researching, we can find this method is an effective practical method.
