摘要

[目的] 为了探讨离子固化剂路邦EN-1对黄土性土壤的固化性能。[方法] 对土、风沙土、黄绵土、黄棕壤4种土在不同固化剂掺量、养护龄期的固化进行了直剪试验。[结果] 路邦EN-1固化剂可以有效提高4种土壤的抗剪强度

特别是大幅度提高了和黄棕壤的黏聚力。[结论] 固化剂的掺量并非越大越好

掺入量过多反而会降低土壤的抗剪强度。掺量为0.01%

养护时间为28 d时固化效果最佳。路邦EN-1固化剂适用于黏粒含量较大的土壤

不适用于砂粒含量较大的土壤。

Abstract

[Objective] To investigate the solidifying capability of soil stabilizer EN-1 on loess soil.[Methods] Direct shear experiments with 4 loessial soils of Lou soil

sand soil

loessal soil and yellow brown soil

with different solidifying agent content and curing age are conducted.[Results] EN-1 can improve the shear strength of the four types of soil

especially the cohesion of soil in Yangling District and Ankang City.[Conclusion] The amount of EN-1 needs to be appropriate

as excessive amount of EN-1 may reduce the shear strength of soil. The optimal amount of EN-1 is 0.01%

and the optimal curing age is 28 d. Soil stabilizer EN-1 is more suitable for soil with high clay content

rather than soil with high sand content.
