Gravel Pile Underwater Model Test And Numerical Simulation

Vibro stone pile technique has its economy, stability, construction and simple and so on,it canbe widely used in practical engineering and promotion of road foundation treated.But the lack ofthe current research in a variety of characteristic index of the underwater gravel pile bearingcapacity and settlement, etc.And underwater gravel pile to a variety of uncertainties researchand understanding the working mechanism is also more vague,We are currently underwatergravel pile to rely mainly on the road foundation design experience and engineering analogy.Sowe pile foundation work to strengthen the mechanism of underwater gravel pile to,CalculationTheory,These studies further improve the quality of vibro foundation works have a highpractical significance.In this paper, we first analyze the gravel pile to technology at home and abroad,Researchconditions and applicable conditions,We point out shortcomings and problems in practicalengineering techniques exist gravel pile.Our research focuses on the gravel pile to pile works,among piles of soil bearing capacity to analyze relationships.In terms of carrying capacity，Thisarticle is similar to the relationship between the physical destruction of gravel pile in the indoormodel test study of the mechanism of destruction pile of rubble piles.According to the results ofmodel tests，We study and analyze the factors affecting gravel pile lateral friction and pile tipresistance，In addition, we study analyzed the relationship between the curve and the lateralfriction pile tip resistance between the external load.we coefficients were corrected the Capacitycalculation formula given in the specification.Then we give the formula of gravel pile to pilecapacity correction.Secondly, through the ABAQUS finite element software, we haveestablished a gravel pile to pile calculation model,We analyze the model under the rubble pileloads of stress and displacement changes.
