| 摘 要： | 生态护坡技术是一种日益被重视的护坡方法。生态土壤稳定剂是一种既能稳定土壤,又能促进植物生长的新型土壤改性材料。以宁淮高速公路某段路堑边坡作为试验段,应用自主研发的一种新型生态土壤稳定剂对试验段进行护坡绿化,采用FLAC-3D模拟计算软件分析了膨胀土路堑边坡表层改性土的强度及厚度变化对边坡整体稳定性的影响。研究表明,生态土壤稳定剂除了能防治坡面因冲刷而造成的水土流失、有利于植物生长外,还能提高边坡的整体稳定性。

| Abstract: | The ecotype technology of slope protection is being used more and more widely.Ecotype soil stabilizer is a kind of newly developed soil modification material,which can not only stabilize soil grains but also promote plant growth.In this paper,an independently developed ecotype soil stabilizer was adopted in a test expansive soil slope located in Ning-Huai expressway,and the influence of shear strength and thickness variation of the slope surface soil layer modified by the soil stabilizer on the slope stability was analyzed with FLAC-3D numerical simulation software.The research indicates that ecotype soil stabilizer not only can prevent soil erosion from the slope wash out and benefit plant growth,but also can raise the stability of a slope. |
