Abstract: This paper uses the binomial stationary stochastic process to describe vehicl load (axial load) in the design of bridge and Culvert structures. By analyzing the information of vehicle load investigation, we can obtain the probability distribution in the basic design lifetime and the standard load as well.

摘要： 本文提出用二项平稳随机过程来描述桥涵结构设计中的车辆荷载(轴重),通过车辆荷载的调查数据的分析,来得出桥涵在设计基准使用期内经受的车辆荷载的概率分布。标准荷载也可考虑据此得出。
