The relationship between the calculation formulas of pile-soil stress ratio and the negative friction area on piles considering the interaction of pile-soil-cushion was deduced. This calculation formula is evaluated and confirmed through tested example.
对刚性桩复合地基现有的常用桩土应力比计算公式的研究现状做出归纳总结,依据刚性桩复合地基的变形模式和特点,推导出刚性桩复合地基在考虑桩—土—垫层的相互作用时的桩土应力比n与负摩阻区深度l_0之间的计算关系式,并结合工程实例对公式进行评价性验证。
