利用FLAC3D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。
利用FLAC3D數值倣真軟件,建立土工格室-樁-樁週土相互作用數值倣真模型,對比分析土工格室+階梯型變截麵樁複閤地基與土工格室+等截麵樁複閤地基的承載性狀。研究結果錶明:土工格室+階梯型變截麵樁複閤地基的樁體平均沉降、土體平均沉降及樁土平均沉降均小于土工格室+等截麵樁複閤地基。

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.
