Designed by the Hunan Provincial Electric Power Surveying and Design Institute and constructed by Wu Ning Construction Engineering Co., Ltd., No. 2 cooling tower of Xiaoguang Power Plant, Changguang Coal Mine, with a total height of 60 meters, is a simplified structure of double-curved cast-in-place reinforced concrete natural ventilation, with a bottom diameter of 58.82 meters. The inner diameter of the neck is 24 meters, the top diameter is 27.038 meters, and the showering area is 1500 meters~2. The whole cylinder body is supported by 72 mandrel columns that support the ring beam from the bottom ring beam, and the load is transmitted to the foundation. The wall thickness of the cylinder is The 35 cm of the ring beam is tapered to 12 cm in the cylinder, and the middle and upper parts are 12 cm. The main geometry is shown in Figure 1.
