Intelligent control method of temperature stress and transverse joint behaviors of concrete arch dams

Preventing temperature cracks and regulating the working behaviors of transverse joints are two crucial issues in arch dam construction, and a reasonable cooling strategy is key to an effective solution. This paper describes a new intelligent method for controlling temperature stress and transverse joint behaviors and the application of its control concept, simulation analysis tools and automatic control technology, and develops an intelligent control system of arch dam construction. Analysis shows this system effectively controls the dam body stress and the working behaviors of transverse joints and gives full play to the performance of concrete materials, greatly improving construction efficiency. We have achieved the optimization goal of intelligent temperature crack control and intelligent transverse joint behavior adjustment.
