介绍了有关土压力作用机理和各国散粒货物侧压力的计算公式及其压力图形,并运用土压力理论对运行工况和调车工况下敞车端墙、侧墙承受散粒货物侧压力的作用机理进行了综合分析,重点分析了运行工况振实阶段的类液态机理和类固态机理,建议在敞车端墙、侧墙强度计算中使用土压力水平地震力的有关计算公式进行计算。
This paper introduces the mechanism of earth pressure and the calculation formula of the lateral pressure of the bulk cargoes in different countries and its pressure pattern, and applies the theory of earth pressure to the end wall and the side wall of gondola under the operating conditions and shunting conditions to bear the side pressure The mechanism of liquid-like mechanism and the solid-like mechanism are analyzed emphatically during the working-up phase. It is suggested that the calculation formula of earth-rock level seismic force be used to calculate the strength of end-gantry and side wall.
