圆形煤场的设计要满足结构布置和构造措施要求。结合鸿山热电厂二期圆煤场网壳设计,介绍了风洞试验的模型和试验结果,进行了结构动力分析,并针对不同堆煤状态对上部结构进行了计算分析。结果表明:近海地区,风荷载仍然是上部结构的主控荷载。应考虑周边环境对煤棚的影响,进行风洞试验。堆煤状态计算不可忽略,必须建立整体模型分析不同堆煤状态对上部结构的影响,设计取各工况下的包络值。支座的理论假定应符合实际受力情况,并结合下部结构的受力特性综合确定,建议采用单项滑动支座,并限制最大滑移。
The design of circular coal yard shall meet the requirements of structural arrangement and construction measures. Combined with the design of the second-phase coal yard reticulation shell in Hongshan Thermal Power Plant, the wind tunnel test model and test results are introduced, the structural dynamic analysis is carried out, and the superstructure is calculated and analyzed according to the different coal accumulation status. The results show that in the offshore area, the wind load is still the main load of the superstructure. Should consider the impact of the surrounding environment on the coal shed, wind tunnel test. The calculation of coal accumulation status can not be neglected. The overall model must be established to analyze the influence of different coal accumulation conditions on the superstructure. The envelope value of each condition should be designed. The theoretical assumptions of the bearing should be consistent with the actual force situation, combined with the force characteristics of the substructure to determine a comprehensive, it is recommended to use a single sliding bearing and limit the maximum slip.
