Temperature Control Sensitivity Analysis and Research on Thin-walled Hydraulic Tunnel Lining Concrete
The phenomenon of concrete cracking is a major problem plaguing the engineering community, and one of the major factors causing cracking is temperature loading, while thin-walled concrete, such as hydraulic tunnel lining and other similar projects, makes the impact of this phenomenon more prominent due to its special structure and role. To address this problem based on the concrete temperature field theory, combined with the three-dimensional finite unit method of temperature control methods in engineering analysis and research, it is concluded that surface water conservation and water cooling can effectively reduce the base temperature difference to reduce the temperature stress; early low temperature water flow may cause excessive temperature gradients, resulting in large temperature stress; surface insulation layer can be applied to effectively mitigate the rate of temperature drop and environmental temperature changes on the concrete.
