摘要
对CFG桩复合地基的褥垫层机理及合理厚度进行了分析,提出褥垫层施工控制的要点,结合实例,利用推倒公式来确定褥垫层厚度,说明合理的褥垫层厚度可以提高CFG桩的承载力和抗变性能,并达到降低工程造价的目的。
The mechanism of cushion as well as rational thickness of cushion in composite foundation of CFG pile is analyzed,at the same time key points for construction control of cushion are proposed.Combined with construction example the thickness of cushion is determined utilizing push-over formula.Author points out that proper thickness of cushion can increase the bearing capacity and anti-deformation properties of CFG pile to reduce engineering cost.
