针对大型水闸闸墩混凝土施工期温度控制与防裂比较困难的问题,同时考虑夏季高温施工的不利情况,以河口村水库溢洪道闸墩为例,基于温度场和应力场的三维有限元分析方法,通过研究入仓温度、通水冷却、后浇带等因素对闸墩开裂的影响,提出了控制入仓温度、通水冷却与设置后浇带相结合的温控防裂措施。结果表明,本文提出的温控措施效果较好。 In view of the difficulty of temperature control and crack prevention during the construction of large sluice piers, taking into account the unfavorable conditions of high temperature in summer, Taking the spillway pier in Hekou Village as an example, based on the three-dimensional finite element method of temperature field and stress field, By studying the impact of warehousing temperature, water cooling, post-pouring and other factors on cracking of sluice piers, a temperature control and crack prevention measure was proposed to control the warehousing temperature, water cooling and post-pouring zone. The results show that the proposed temperature control measures are better.
