为了快速得出碎石桩加固软土地基条形基础的极限承载力,基于Morgenstern-Price切片法建立了碎石桩改良软粘土承载力的分析模型,以此进行参数研究,并进行Gauss和线性拟合.研究结果表明所建立的分析模型取得了较好的结果,当间距/直径比(S/D)等于 1.4 时可以取得最好的改良效果,改良率(IR)随着置换率的增加而显著增加,并且参数与改良率(IR)的拟合结果具有较高的精度,为碎石桩加固软土地基条形基础的应用提供科学依据.
Research on Bearing Capacity of Strip Foundation Reinforced by Gravel Pile in Soft Soil Foundation
In order to quickly determine the ultimate bearing capacity of gravel pile reinforced soft soil strip foundation,this paper establishes an analysis model for the bearing capacity of gravel pile improved soft clay based on the Morgenstern Price slicing method.Based on this analysis model,parameter research was conducted and Gaussian and linear fitting were performed.The research results indicate that the established analysis model has achieved good results,and the best improvement effect can be achieved when the spacing/diameter ratio(S/D)is equal to 1.4.The improvement rate(IR)significantly increases with the increase of permutation rate,and the fitting results of parameters and improvement rate(IR)have high accuracy,which provides a scientific basis for the application of crushed stone pile reinforcement of soft soil strip foundation.
