前言本文主要通过对塘沽新港淤泥质亚粘土的两个试样分析来研究该类土的宏观、微观特性,为深入了解海粘土的性质、同时也介绍了对海口湛江组粘土的研究结果。一、样品的宏观特征样品取自塘沽新港某工程、样品埋深分别为5.7—5.9米(977~#)和6.1—6.3米(978~#)。1.样品为淤泥质亚粘土与粉砂薄层或透镜体交错成层。977~#样上部的粉砂层呈薄层状,下部为较厚的粉砂层透镜体,粉砂含较多的贝壳碎片。上述的上体结构特点不仅造成工程性质的各向异性,就是同一土样的不同部位其性
Foreword This article mainly analyzes the macroscopic and microscopic characteristics of this type of soil through analysis of two samples of muddy sub-clay in Tanggu Newport, in order to have a deep understanding of the properties of sea clay, and also introduces the research results of clay in Zhanjiang Formation in Haikou. First, the macroscopic characteristics of the samples Samples taken from a project in Tanggu New Harbor, the depth of the sample were 5.7-5.9 meters (977 ~ #) and 6.1-6.3 meters (978 ~ #). 1. The sample is a staggered layer of silty sub-clay with a thin silt or lens body. The upper silt layer of 977~# is thin layered, and the lower part is a thicker silt layer lens body. The silt contains more shell fragments. The above features of the upper body structure not only cause the anisotropic nature of the engineering, but also the different parts of the same soil sample.
