摘　　要：腐木土层是滨海相浅水环境下形成的沉积物,它是一种特殊的软土层,工程性质差,不同时代腐木土层的工程性质不同。土体结构类型是制约公路路基沉降变形的主要因素。腐木土层分布区划分出三种土体结构类型,具有不同的沉降变形特征不同。Rot wool sitl layer is a deposit formed in shallow environment of littoral facies. In different periods layers of silt with rot wood have varied types of engineering characteristics, soil body structures and conditions of engineering geology. The type of soil body structure is main element that restricts the sediment and deformation of a highway foundation. The distribution zones of layers of silt with rot wood can be partitioned to three types of soil body structures. They have different characteristics of sediment and deformation. So the measures for treating these foundation should be different.
