摘要
腐木土层是一种特殊的软土层。不同时代的腐木土层的工程性质及土体结构类型不同,工程地质条件也不同。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,地基措施方式也应不同。
With poor engineering characteristics a layer of silt with rotten wood is a special type of soft soll layer. It is a deposit formed in shallow environment of littoral facies. In different periods layers of silt with rotten wood have different engineering characteristics, soll body structures and conditions of engineering geology. The type of soil body structure is main factor that affects the sediment and deformation of a highway foundation. The distribution zones of layers of silt with rotten wood can be subdivided into three types of soil boy structures. They have different characteristics of sediment and deformation. So the measures for treating these foundations should be different.
