| 摘 要： | 对STW型生态土壤稳定剂改性重塑土在不同掺量、不同制备方法及不同养护条件下的强度变化进行了试验研究。试验结果表明:STW型生态土壤稳定剂对重塑土无侧限抗压强度具有明显的增强效果,并与试样的制备方法、稳定剂掺量及养护条件有关;5%的掺入量改性效果最佳;在室温下养护72小时其强度提高幅度最大。同时,还对STW型生态土壤稳定剂土质改性机理进行了分析。

| Abstract: | In this paper,the unconfined compressive strength tests of the remolded soil modified by STW ecotypic soil stabilizer were performed under the different addition,making methods and curing conditions.The test results indicate that STW ecotypic soil stabilizer enable the strength of remolded soil to increase and the strength increament has closely relationship with the making methods of the sample,addition of the STW and curing conditions;the addition dosage of 5% STW is optimal for the modified effect and 72 hours curing in the indoor temperature makes the sample strength reach to the maximum.Finally the modified mechanism of STW ecotypic soil stabilizer was analyzed. |
