摘要
二灰土在高等级公路底基层中得到广泛应用,但是对二灰土渗透特性的研究较少。通过二灰土的基本物理性质试验,系统地研究含水率、压实度这两个因素对二灰土的抗压强度及渗透性的影响,获得二灰土压实度与渗透系数及无侧限强度之间的关系特点。
Lime-ash soil is used widely in the base layer of high-level road,but little study is done on permeability performance of the soil.The study of the basic physical properties of lime-ash soil is developed.However,after studying the influences of the moisture content,degree of compaction on the compression and the permeability of lime-ash soil and analyzing the relationship between degree of compaction and unconfined shear strength of lime-ash soil,we come to a result that the basic physical parameters of lime-ash soil may change a lot even within specification requirements by many experiment of basic physical characteristic of lime-ash soil.
