| 摘 要： | 针对不同级配的粉土、黏土,进行了粉土、黏土的击实特性试验和渗透特性试验研究,绘制了不同击实功作用下和不同级配粉土、黏土的干密度曲线,得到了不同击实功作用和不同级配的粉土、黏土干密度变化规律,探讨了不同压实度的粉土、黏土的渗透特性。试验结果表明:不同级配的粉土、黏土中存在一个最佳击实功,并且在该击实功下,可获得其最大干密度;与此同时,黏土可以通过掺入粗颗粒改变其压实特性,而对于粉土,通过掺入粗颗粒改变级配,并不能有效地改变其压实特性;填土的渗透特性随着压实度的增大而呈现非线性变化。

| Abstract: | In this paper,the compaction and seepage tests of silt and clay soil are presented with the drawings of the dry density curves of silt and clay soils under different compact efforts and different sized ground fills to investigate the compaction property of highway's ground fill foundation. Also,the seepage property of compactness silt and clay soils is discussed. It shows that an optimal compact effort can be obtained in different gradations of silt and clay soils. The maximum dry density can subsequently b... |
