摘要：

车辆在运行中因擅自改装和超栽往往会引发道路交通事故，但对于停驶状态的货车发生侧翻与车辆改装和超载是否存在因果关系呢，根据一起货车侧翻的实际案例，通过对栽货货车的质心计算、货车侧翻机理分析、货车车厢加长和超载状态与货车稳定性之间的关系分析，得出货车车厢加长和超载使货车栽货后的整体质心升高并同时后移，降低了货车的稳定性。货车车厢加长和超栽是导致货车发生侧翻的直接原因。

Abstract:

Unauthorized truck modification and overloading always result in road traffic accidents. Based on the data from a real truck roll-over accident, this paper calculated the centroid of the loaded truck, analyzed the roll-over mechanism, and obtained the relationship between the overloading weight and the stability of the loaded truck. In conclusion, it is determined that lengthening the truck and overloading make the centroid lift up and move backwards, and eventually cause the roll-over of the truck.

Key words: roll-over, overloading, vehicle modification, centroid, stability, critical cargo weight
