中文摘要：

为满足工程建设的需要,对某市高新区表土层进行了渗流固结和直剪试验研究。试验测定了土体的基本物理性质指标并命名为粉质粘土;在一维固结渗流试验中测定得出土体的压缩系数为0.38 MPa-1、压缩指数为0.28,确定土体为中性压缩性土;得到了土体在各级压力下的变形曲线和竖向应变;在直剪试验中测定了土体在不同竖向压应力下的抗剪强度及土体的粘聚力和内摩擦角,为该地区的工程建设及建筑物的沉降分析提供了土体的基本参数。

英文摘要：

In order to meet needs of engineering construction,seepage consolidation and direct shear tests of surface soil from a high-tech zone in a city were carried.The indicators about the basic physical properties of the soil were determined,and called as silty clay in the test.In the one-dimensional seepage consolidation test,tested compression coefficient of the silty clay is 0.38 MPa-1,tested compression index of it is 0.28,it was identified as neutral compressive soil,and the deformation curves and vertical strain under pressure at all levels were obtained.In the direct shear test,the shear strength of the silty clay under different vertical pressures and its gotten cohesive strength and internal friction angle were determined.These tests provided the basic parameters of soil for the engineering construction and settlement analyses of buildings in the region.
