| 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(土娄)图土、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(土娄)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28d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. |
