【摘要】 本文分析了低承台复合桩基在承台作用下的桩-承台-土的共同工作机理，具体分析了它的荷载传递变化及其桩周土受荷变化，从中得出承台的作用使桩侧摩阻力，桩端阻力均有提高。更多还原

【Abstract】 This paper is analysed the mechanism of pile-capping-carth working together under the function of capping in low capping-composite pile foundation, the variation of its loading transmission and the variation of the earth around the pile caused by loading.It can be proved that the function of pile capping could improve the lateral frictional resistance of pile and the end resistance of pile.更多还原
