[目的] 探讨EN-1固化剂对土壤抗崩性的影响
为固持河岸边坡提供理论依据。[方法] 应用室内静水崩解试验
研究添加EN-1固化剂比例为0(素土)
0.05%
0.10%
0.15%
0.20%和0.30%水平时
分别在压实度0.85
0.90和0.95状态下
养护3
7和15 d的崩解量和崩解速率。[结果] 在试验设计的EN-1固化剂掺入量、养护龄期和压实度范围内
随EN-1固化剂掺入量的增加、养护龄期的延长和压实度的增大
固化土的崩解量较素土显著减小。[结论] 从固化剂的有效利用率和经济的角度考虑
当EN-1固化剂掺量为0.20%时
养护龄期为7 d及以上时
压实度为0.90及以上时抗崩解固土性能较好。
[Objective] To measure the effect of EN-1 soil stabilizer on soil anti-collapse ability in order to provide the theoretical basis for immobilizing the bank slope. [Methods] By utilizing indoor disintegration experiments in static water
disintegration amount and disintegration rate were studied under certain conditions which included the proportion of EN-1 soil stabilizer at 0(pure soil)
0.05%
0.10%
0.15%
0.20%
and 0.30%
the compactness at 0.85
0.90
and 0.95
and the maintaining period during 3 d
7 d
15 d
respectively. [Results] Solidified soil disintegration amount decreased significantly compared with pure soil along with the increasing amount of EN-1 stabilizer and maintaining period which were designed in experimental scheme. [Conclusion] With the view of the effective utilization rate and economy
soil-reinforcement is significant when the appropriate proportion of stabilizer was 0.20%
the maintaining period was at least 7 days
and the compactness was no less than 0.90.
