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 plant growth to improve the ecological slope protection.
