摘要
利用FLAC^(3D)数值仿真软件,建立土工格室-桩-桩周土相互作用数值仿真模型,对比分析土工格室+阶梯型变截面桩复合地基与土工格室+等截面桩复合地基的承载性状。研究结果表明:土工格室+阶梯型变截面桩复合地基的桩体平均沉降、土体平均沉降及桩土平均沉降均小于土工格室+等截面桩复合地基。
Establishes the numerical simulation model for interaction of geocell, piles and soil around piles by simu-lation software FLAC3D, contrasts and analyzes the bearing capacities of the composite foundation with geocell ＋ step variable section piles and the composite foundation with geocell ＋ constant section piles. The results indicate that the composite foundation of geocell ＋ step variable section piles is superior to that of geocell ＋ constant section piles in average pile settlement, soil settlement and pile-soil settlement.
