摘要
采用有限差分软件FLAC3D对普通桩、刚性排水桩和碎石桩加固液化地基进行数值模拟,分析了3种桩体加固液化地基的抗液化效果。研究表明刚性排水桩和碎石桩抗液化能力显著,但距桩中心的不同距离和不同土层深度抗液化效果有所不同。
Finite difference software FLAC3D is used to simulate the liquefaction foundation strengthened by ordinary pile,rigid drainage pile and gravel pile,and the anti-liquefaction effect of three kinds of piles is analyzed.The results show that the anti-liquefaction ability of rigid drainage pile and gravel pile is remarkable,but the anti-liquefaction effect is different at different distance from the center of pile and at different depth of soil layer.
