散粒货物对敞车墙壁压力作用机理的分析(续完)

Analysis of Mechanism of Pressure Applied by Bulk Goods on Walls of Gondola Cars(Last Part Continued)

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。

The earth pressure application mechanism,the calculation formulae diagrams of the lateral pressure of bulk goods in various countries are described.With the earth pressure theory,the application mechanism of bulk goods upon the end walls and side walls of gondola cars is analyzed comprehensively under the working conditions of operation and shunting.The liquid-like mechanism and solid-like mechanism in the jolt stage of operation are mainly analyzed.It is suggested to use the relevant calculation formulae of horizontal seismic force of the earth pressure in the strength calculation for end walls and side walls of gondola cars.
