| 摘 要： | 利用路邦土壤固化剂对四川遂宁地区红砂岩进行了固化试验研究,根据不同固化剂掺入比和不同龄期时固化土的无侧限抗压强度试验结果,结合施工便易性,分析了不同掺入比、龄期对红砂岩固化土强度的影响。试验结果表明:路邦土壤固化剂固化红砂岩的最优掺入比为0.014%,最优掺入比下28龄期固化土的强度约为素土强度的3.49倍。对最优掺入比下的固化土进行水稳定性试验,发现固化土的水稳系数由素土的0提高为0.87,具有了很好的水稳定性。

| Abstract: | The experiment study on stabilized red sandstone in Suining, Sichuan province, by EN-1 soil stabilizer is conducted. According to different mixing ratio of different stabilizer, and the experimental results of unconfined compression strength in different age, combining with easiness of construction, the influence of different mixing ratio and age on the strength of sandstone soil is analyzed. The result shows that the optimal mixing ratio is 0. 014%, the optimal mixing ratios of the strength of solidified soil is about 2.45 times the strength of original land. The water stabilizing experiment of solidified soil in the optimal ratio shows that its water stabilizing coefficient is raised from 0 to 0.87 compared with than that of original soil, which displays its good water stability. |
