Abstract
With the rapid development of China’s chemical industry in coastal areas, the transportation of hazardous chemicals has become increasingly busy. Due to the complexity of marine environment, there are a large number of safety hazards during the transportation of hazardous chemicals. Based on accident statistics, the main factors affecting the transportation safety of hazardous chemicals is analyzed, including strong wind and reduced adhesion coefficient caused by rain and snow. Further, a vehicle stability analysis model considering these factors is established to calculate the critical wind speed of sideslip. Finally, the speed of the hazardous chemical vehicle is used as the safety evaluation index, and the safety critical speed surface is given. This research has important reference value for ensuring the transportation safety of hazardous chemicals and the operation of cross-sea bridges.
