土工格栅碎石桩的承载力分析

Analysis on the Bearing Capacity of Geogrid Reinforced Stone column

摘要: 利用极限平衡理论对土工格栅碎石桩进行了分析。结果表明，由于桩体侧向压力和轴向力沿桩长的非线性分布，导致桩体膨胀破坏的破裂面产生于距桩顶深度１～３倍桩径的部位。土工格栅对碎石桩承载力的提高有显著的影响

Abstract: The geogrid reinforced stone column is analyzed by using limit equilibrium theory.Results show that the rupture plane as expanding break is located at the depth of about (1～3) radius of stone column due to the nonlinear distribution of lateral pressure and axial force. The geogrid increases the bearing capacity of stone column remarkably.
