| Abstract: | This paper mainly discusses the establishment and the detailed content of the mechanical analytical model of pipeline and soil under dynamic and static loads both in China and abroad at present.The characteristic of the mechanical analytical model of pipeline and soil under traffic loads,such as randomicity,dynamic,coupling and non-linearity,are analyzed.which provides certain basis for further discussion of the mechanical properties of pipeline in soft soil under traffic loads. |
