Law of vehicle load diffusion in high fill culvert
This paper mainly introduces the diffusion mode and calculation method of the automobile load effect assumed and borne by the high filling earth covered slab culvert.The vehicle load and diffusion area of the cover culvert with different fill height are analyzed and the multi-lane reduction factor is considered.The results show that when the culvert is designed with multiple lanes,the two-lane force is the most unfavorable.The vehicle load effect decreases with the increase of filling height.At the same time,the diffusion law of load effect of high fill cover culvert is summarized to provide reference for similar projects.
