摘要
地面汽车荷载对覆土层下管线的影响主要通过车轮压力扩散模型来计算,论文提出一种简化计算,得出不同等级公路所对应的管线掩埋深度值及压力大小,为施工设计提供参考。
The influence of the ground vehicle load on the pipeline under the overburden layer is mainly calculated by the wheel pressure diffusion model.This paper proposes a simplified calculation to obtain the buried depth and pressure of the pipeline corresponding to different levels of highway,which provides reference for construction design.
