| 摘 要： | 介绍了STW型生态土壤稳定剂对宁淮高速公路边坡膨胀土的胀缩性、水稳性、强度、抗冲刷性等的改性试验研究,并结合现场试验,分析了STW型生态土壤稳定剂用于膨胀土边坡坡面防护的效果。试验结果表明:STW型生态土壤稳定剂改性膨胀土的胀缩性,随着稳定剂掺量的增大而减小;改性土的水稳性,随着稳定剂稀释浓度的增大而增强;同时,改性土的强度得到显著提高,抗冲刷性能得到明显增强,具有显著的防治水土流失、促进表层固化、提高坡面稳定的效果。

| Abstract: | In this paper,a series of soil improvement tests with STW soil stabilizer for expansive soil slopes of Ning-Huai expressway are presented.The results indicate that the swell-shrinking property of the expansive soil modified by STW soil stabilizers is reduced while its water stability,strength,erosion resistance are increased.And the swell-shrinking property of the modified soil decreases when the mixing amount of STW soil stabilizer is increased.The STW soil stabilizer can decrease soil loss and promote pla... |
