Numerical Experimentation of the Underground Pipeline Anti-To Float in Liquefaction Field with Gravel Draining Water Layer

This paper applied a gravel drainage layer around an underground pipeline. Based on the Finn model, the numerical liquefaction experiments were completed separately in the non free field and the gravel drainage layer non-free field. The paper confirmed the anti-float effect of the gravel drainage layer method. Calculations indicated that, the gravel drainage layer field around the underground pipeline will not liquefy, the excess static pore pressure obviously reduced at far place from pipeline in liquefaction field, the pipeline uplift obviously reduced, and the level drifting reduced. The gravel drainage layer has enlarged the overall quality and the rigidity of the pipeline, as well as increased the pipeline's stability. Researching results will provide a theoretical and experimental basis for the design of underground pipeline through the liquefaction soil layer.
