整体式封闭煤场挡煤墙结构,堆煤产生的内外壁温差及季节温差对结构的配筋设计有着巨大的影响,封闭煤场基础环梁及挡煤墙结构的配筋多由堆煤侧压力及温度应力的组合工况控制.本文根据现场测试及试验的结果,提出封闭煤场堆煤内外壁温差、季节温差及温度应力计算的取值原则,同时对混凝土结构的裂缝宽度控制标准提出了建议. The overall enclosed coal yard retaining wall structure, the inner and outer wall temperature difference caused by the stacking of coal and the seasonal temperature difference have a tremendous impact on the reinforcement design of the structure. The reinforcement of the foundation ring beam and the retaining wall structure of the enclosed coal yard mostly consists of the coal side Pressure and temperature stress.On the basis of field test and test results, this paper puts forward the principle of calculating the temperature difference between inside and outside wall, the seasonal temperature difference and the temperature stress in the closed coal yard, and puts forward the control standard of the crack width of the concrete structure Suggestion
