Continuous Rigid structure Construction Temperature Control

This article combined with the construction project, analysis long-span continuous rigid high-strength structural concrete bridge span in the construction process, temperature changes influencing factors ,temperature changes the most prominent symptoms; through research and structure of materials performance tests on-site detection, to get concrete mix ratio and a series of technical parameters, Concrete temperature by the time value of live tracking and detection data for statistical analysis, derived concrete temperature changes in laws and Eigen values; proposed continuous rigid structural concrete construction of temperature control points, control methods, operation process and temperature cracks precautions. Engineering practice shows that the continuous rigid frame construction of the concrete temperature caused by the temperature difference between stress and cracks must attach great importance to be effectively controlled from the technical.
