针对滑模快速施工条件下混凝土闸墩温控防裂问题,以官地水电站表孔闸墩为例,采用仿真计算方法预测并优化了该闸墩施工期温度和应力发展过程。结果表明,在混凝土所处环境温度较高、混凝土结构体积较大、约束大时,二级配混凝土、门槽、溢流面顶部附近的闸墩混凝土、间歇面四个区域易开裂,需加强水管冷却和表面保温措施。 In order to solve the problem of temperature control and crack prevention of concrete piers under the condition of rapid sliding mode construction, taking the pier of Guandi hydropower station as an example, the temperature and stress development process of the pier during the construction period are predicted and optimized by the simulation calculation method. The results show that when the ambient temperature of concrete is high and the volume of concrete structure is large and the restraint is large, the four concrete sections of the concrete, the gate slot and the pier concrete near the top of the overflow surface are easy to crack and need to be strengthened Water pipe cooling and surface insulation measures.
