Analysis of Influence Factors of PHC Pile-net Foundation

摘要

Through ABAQUS software, two dimensional plane strain model is used to analyze the half-amplitude roadbed. The variations of vertical displacement of fill surface, side displacement of levee toe are investigated in relation to the varying fill height, pile length, distance of two piles etc; leading to the conclusion that of the higher the fill height is, the larger the penetration coefficient of the soils, vertical displacement of fill surface and side displacement of levee toe are; as well, the larger the pile length and the less the distance of piles are, the thicker the reinforcement sand cushion is, the more the modulus of compression in supporting course is and with the vertical displacement of fill surface, the side displacement of levee toe becomes insignificant.
