摘要

为了研究EN-1土壤固化剂的固化性能

通过室内模拟实验对杨凌、安康、安塞和靖边4种土壤在不同固化剂掺量、养护龄期的固化进行了土壤饱和导水率影响的研究

结果表明

微量掺加EN-1固化剂就可以明显减小黄棕壤和土的饱和导水率

饱和导水率随着培养龄期的增加而下降

当培养期大于14d时土样的饱和导水率近似为0;黄绵土与风沙土的饱和导水率随着固化剂掺量增加而减小

培养龄期增大

饱和导水率随之下降

固化剂掺量为1%

培养期为28d时黄绵土和风沙土的饱和导水率最低。

Abstract

In order to estimate soil solidification performance of EN-1 solidifying agent

saturated hydraulic conductivities for four types of soils collected from Yangling

Ankang

Ansai

and Jingbian in Shaanxi Province were investigated by indoor simulation test with different solidifying agent contents and curing ages.Results indicated that traces of EN-1 solidifying agent added in the tests can considerably reduce saturated hydraulic conductivities of yellow brown soil and Lou soil.The saturated hydraulic conductivities decreased rapidly with the increased curing age and dropped to zero when curing age was more than 14 days.Saturated hydraulic conductivities of loessal soil and sandy soil decreased not only with the increased addition of the solidifying agent

but also with the increased curing age.The saturated hydraulic conductivities of loessal soil and sandy soil were the lowest at the 1% EN-1 solidifying agent after 28 days curing.
