摘　　要：用十字板测定软土夹层抗剪强度指标,计算地基的变形和塑性区域,并根据计算结果探讨软土夹层地基塑流失稳的界限,提出了相应的估算公式.The shearing strength of soft layer determined by cross—board is used for calculating the deformation and the plastic zone of foundation in this paper.According to these results,the demarcation for embankment failure caused by plastic flow of soft layer is studied and corresponding estimate formulas are also proposed.

关 键 词：软土地基 塑性流动 软土夹层 测定 地基变形 塑流失稳界限
