多桩型复合地基作为复合地基技术的新发展,在工程实践中得到愈来愈多的应用,被列入《建筑地基处理技术规范》JGJ79报批稿,但其承载力计算复合式中桩与桩间土承载力发挥系数,不同条件的多桩型复合地基应有不同的取值。本文依据现场实测结果对刚性长短桩复合地基承载力发挥系数进行的分析表明,多桩型长短桩复合地基桩间土承载力发挥系数可为1.0,增强体单桩承载力发挥系数可取0.8～0.95。
Multi-pile composite foundation as a new development of composite foundation technology, more and more applications in engineering practice, has been included in the “Building Foundation Treatment Technical Specifications” JGJ79 draft for approval, but its capacity to calculate composite piles and piles Soil bearing capacity between play coefficient, different conditions of multi-pile composite foundation should have different values. Based on field measurements, this paper analyzes the factors that affect the bearing capacity of rigid long and short piles composite foundation. The results show that the coefficient of bearing capacity of multi-piles long and short piles composite foundation can be 1.0, and the coefficient of bearing capacity of single pile reinforced can be 0.8 ~ 0.95 .
