半刚性碎石桩复合地基桩土应力比的研究

Research on Stress Ratio of Pile to Soil in Semi-rigid Stone Column Composite Foundation

阐述了复合地基桩土应力比的计算理论 ,分析了半刚性碎石桩复合地基桩土应力比的工程实测结果 ,运用理论计算公式对半刚性碎石桩复合地基的桩土应力比进行了计算 ,并将两者进行了对比 .在充分考虑桩间土应力折减的基础上 。

This paper discusses calculating theory of stress ratio of pile to soil in composite foundation, analyses its engineering data, and calculates stress ratio of pile to soil on the basis of theoretical formula, and compares theoretical value with engineering value. A new formula is established in order to reflect stress reduction.
