摘要

为了在渠道防渗工程中推广应用新型土壤固化剂

基于关中黄土引入了几种不同类型的固化剂。从击实、无侧限抗压、渗透、冻融等方面进行了固化土性能试验。结果表明

黄土在掺用了固化剂后

最优含水量有所降低

最大干密度得到提高

压实性能向好的方面发展。在浸水条件下

不同类型固化土28d强度有所不同

从0强度到3.37MPa不等;固化黄土的渗透系数在8.59×10

-6

～1.81×10

-7

cm/s之间。填加不同固化剂的固化土对抵抗冻融循环的次数不尽相同

最大可达到20次。总之

将固化土直接用做渠道面层防渗材料

其耐久性远不如混凝土

但好的固化土具有的基本性能

也为其作为复合防渗材料的一部分或在低等级渠道防渗工程中使用提供了可能。

Abstract

Several new-style soil consolidator are int roduced according to the loess properties of Guanzhong area in Shaanxi Province.The capacities of the soils mixed with stabilizers were tested

including compaction

unconfined compression strength

seepage and frozen-thawing.The results indicated that their optimal water content decreased;maximum dry density increased;and the compression characteristics had significant effects after the soils were mixed with soil consolidators;the intensities of the soils inundated in water

after 28 days

were separated from 0～3.37 MPa;the seepage modulus is between 8.59×10-6～1. 81×10-7cm/s;and the frozen-thawing times were also different

the ultimate up to 20 times.In short

when stabilized soil is directly used as channel face seepage cont rol material

its endurance is worse than concrete

but it is possible to be used as secondary grade seepage control of canal.
