摘要
目的为提高软土地基的承载能力,促进复合地基理论和技术在工程中的应用.方法在分析碎石桩复合地基所存在问题的基础上,运用理论方法推导了半刚性碎石桩复合地基的极限承载力和桩土应力比,并且与碎石桩复合地基进行了比较.结果在相同的工程地质条件下,将碎石桩加入水泥等材料所形成的半刚性碎石桩,其极限承载力和桩土应力比均高于碎石桩.结论半刚性碎石桩复合地基的加固效果要好于碎石桩复合地基.理论研究表明了半刚性碎石桩复合地基加固软土是可行的.
In order to improve the bearing capacity of the soft foundation and put the theory and the technology of the composite foundation into practice, the authors deduce the ultimate bearing capacity and the stress ratio of the semi-rigid pile column according to the theoretical method, and find that in the same geological situation, the ultimate bearing capacity and the stress ratio of the semi-rigid pile column are both higher than the pile to soil's. So the consolidation effect of the semi-rigid pile column composite foundation is better. It can also be proved that it is practical for the semi-rigid pile column composite foundation to consolidate soft soil.
