摘要
以复合地基桩顶所铺设的褥垫层为研究对象,研究了刚、柔结构层(刚、柔性基础)下褥垫层的受力机理及破坏形式,导出了褥垫层在刚、柔结构层下的合理厚度的理论公式,并确定了其范围,最后通过实例说明了其合理性。
This paper takes the cushion layer paved at the top of the pile of composite foundation as object, analyzing the force mechanism and the destructional forms of the rigid and flexible structure layer （rigid and flexible base）. The formula of the thickness of the cushion layer at the rigid or flexible structure layer has been derived, and the range has been determined. At last, the rationality of the formula has been proved by some live examples.
