Temperature Control Simulation Calculation of Tongguzibulong Reservoir Dam
The focus of temperature control of Tongguzibulong Reservoir dam is the temperature control of concrete pouring in high temperature season and heat preservation in winter.Referring to relevant engineering experience,the temperature control measures of concrete pouring with water cooling in summer and polyurethane as insulation layer in winter are put forward.In order to evaluate the feasibility of temperature control measures,taking No.4 non-overflow dam section as an example,the simulation calculation and analysis of concrete pouring temperature control are carried out by using three-dimensional finite element software.The results show that the temperature control measures during the construction period and the operation period are effective,and the water cooling can reduce the temperature by 3℃～6℃;The maximum temperature stress during the construction period and the operation period does not exceed the allowable stress of concrete,which meets the requirements of the specification.
