摘要

了解三轴渗透试验和常规渗透试验的差异

探求围压产生的应力场对饱和黄土渗透特性的影响规律。对4个典型黄土地区兰州、洛川、杨凌、巩义的黄土试样充分饱和后分别做常规变水头渗透试验和三轴渗透试验。结果表明

随着围压和干密度的增大

饱和黄土的渗透系数减小。从试验得到

当干密度从1.45g/cm3向1.65g/cm3变化时

围压从100kPa向400kPa变化时

三轴渗透试验所得的渗透系数是常规渗透试验所得结果的0.881倍到0.161倍。

Abstract

The difference between conventional permeability test and triaxial permeability test is studied and the characteristics of saturated loess permeability affected by stress field by confining pressure are analyzed.The loess samples from the four typical loess areas of Lanzhou

Luochuan

Yangling

and Gongyi were fully saturated to make conventional variable-head permeability test and triaxial permeability test.Results show that with the increases in confining pressure and dry density

the permeability coefficient of saturated loess decreases.In general

when dry density changes from 1.45 g/cm3to 1.65 g/cm3and confining pressure

from 100 to 400 kPa

the permeability coefficient by triaxial permeability test is almost 0.881 to 0.161 times less than the test result of conventional permeability.
