The Research Of The Temperature Control And Cracking Construction Technology About Ying Shang Lock Concrete

This paper is on the temperature control of mass concrete cracking problems, from the theory and practice of systematic study of the mass concrete temperature field and stress field , and temperature control measures cracking application, and a detailed study and analysis about Yingshang navigation lock mass concrete projects of temperature control problems is carried out .1. Analysis the main reason of a large volume of concrete cracks formed, and studies the temperature control on the occurrence of cracks and control mechanism.2. Temperature field, the stress field of finite element analysis and temperature control involved in the cracking of the theory.3. Temperature cracks in concrete mass concrete construction is one of the important qualities .In the paper, a number of imitation crack temperature control measures are targeted on the basis of simulation.4. Take the lock project of Yingshang for example, monitoring, calculation and the corresponding analysis of the mass concrete temperature and stress are carried out for the construction period under different circumstances.
