运用数值模拟分析方法和理论推导,结合实测数据,提出大直径圆形煤场堆煤荷载、温度作用、地震作用的计算方法和经验数据参考,并对分项荷载提出基于承载力和正常使用极限状态下的荷载组合,以便为数值分析提供输入依据,并将分析所得的各项荷载作用线性叠加形成总内力,确保圆形煤场结构的安全可靠。

By using numerical simulation analysis methods and theoretical derivation,combined with measured data,a calculation method and empirical data reference for the coal stacking load,temperature effect,and seismic effect of a large diameter circular coal yard were proposed.A load combination based on bearing capacity and normal service limit state was proposed,in order to provide input basis for numerical analysis and linearly add the various loads obtained from the analysis to form the total internal force,ensuring the safety and reliability of the circular coal yard structure.
