摘　　要：提出了一种考虑土钉的抗拉作用和搅拌桩的抗剪作用的基坑抗隆稳定分析法。以满足抗隆稳定为基准,提出了最大支护深度的概念,并且提出了土钉支护和复合型土钉支护相应最大支护深度的计算方法。Considered the tensile property of soil nailing and the shearing property of soil-cement mixing pile, the heave-resistant stability method is presented. Based on satisfying the criterion of heave-resistant stability, the maximum depth of retaining and protection, the calculation method of it related to the soil nailing support and the composited soil nailing support are also presented.

关 键 词：土钉支护 复合型土钉支护 最大支护深度
