摘要: 结合工程实践,在阐述刚性桩复合地基受力机理的基础上,对其设计中桩型的选择及其与柔性桩复合地基的综合应用、承载力与变形的计算、桩土应力比与复合地基承载力的关系以及逆作法施工桩基在复合地基施工中的应用等问题作了探讨。Abstract: Based on the exposition of the stress mechanism of composite foundation of rigid piles, some problems in the design and construction are discussed. These problems include the selection of the pile styles, the application of the composition foundation of rigid piles with soft piles together, the computation of bearing capacity and settlement, the relation between the stress radio and bearing capacity, and the application of counter-construction using in composite foundation.
