摘要
褥垫层下复合地基桩间土的沉降大于桩体的沉降。由褥垫层的受力机理导出计算刚性结构层下褥垫层最小厚度的理论公式。
Under cushion the settlement of soil between deep mixing piles (or CFG piles, concrete piles) is bigger than that of the piles. A formula to calculate the minimum thickness of cushion under rigid structural layer was derived by mechanics analysis on the cushion column above the pile.
