刚性基础下柔性桩复合地基的沉降计算

Settlement calculation of flexible piles for composite foundation with rigid foundation

以刚性基础下柔性桩复合地基为研究对象,根据现有的关于桩土应力比的计算方法,对刚性基础下柔性桩复合地基中的桩侧摩阻力的分布形式和规律做了简化处理,并利用Mindlin位移解推导出复合地基沉降的理论解公式。通过工程实例验表明Mindlin位移解沉降计算方法是有效、合理的,为复合地基沉降的计算提供了一种新的方法。

Based on the available computational method of the pile - soil stress ratio, the research simplified the distribution rules and patterns of the pile skin friction for composite foundation with rigid foundation, and derived the calculation formula for settlement of the composite ground from the mindlin displacement solution. The applied case shows that the settlement calculation formula is rational and effective, and provides a new way to calculate the settlement of composite foundation.
