香根草护坡或微型桩护坡在边坡加固与防护工程中均得到了广泛应用;但两者协同护坡却研究很少.边坡安全系数是研究边坡稳定性的主要依据之一,对其计算分析对于预防滑坡具有重要意义.通过在室外建立与实际工程相似的大比例尺试验模型,利用应变片、微型土压力盒等仪器,通过坡顶加载的方法对植被护坡与微型桩护坡的效果进行了模型试验研究.结果表明,植被与微型桩协同护坡能有效的提高坡体整体性,而且能够提高边坡承受荷载能力,为边坡生态与工程协同防护设计提供了借鉴.%Slope protection with vetiver or micropiles were widely used in slope protection and consolidation engineering,but it was seldom researched in the slope protection collaborated with vetiver and micropiles.The slope safety factor has important significance for the prevention of landslide as one of the main basis of slope stability.Through establishing a large scale test model similar to the actual project,the strain gauges and micro earth pressure cells were used to measure data,the effect on vegetation and micropiles on slope protection were researched by model tests through the top surface loading.The results showed that the vegetation and the micropiles would effectively improve the integrity of the slope and improve the load capacity of the slope,which provides a reference for the design of ecological and engineering cooperative slope protection.
