摘要
利用毛细阻滞覆盖层(CB)对边坡进行防护是减小降雨诱发滑坡危害的有效手段之一。毛细阻滞覆盖层不仅在边坡防渗方面有较好的表现,还能满足生态护坡的需要。针对毛细阻滞覆盖层的研究现状,分析了不同因素对其防渗效果的影响,包括几何构造、内部的渗流以及细/粗粒层材料的组成,指出了毛细阻滞覆盖层边坡防护技术的优势与不足,并进一步讨论了提高毛细阻滞覆层防护性能的改进措施和途径。研究表明:CB技术是未来边坡防护与生态护坡的一个重要发展方向。
Using capillary barrier to protect the slope is one of the effective means to reduce the damage of rainfall-induced landslide.Capillary barrier has a good performance in slope anti-seepage, and can meet the needs of ecological slope protection.According to the research status of capillary barrier, the influence of different factors on capillary barrier and its anti-seepage effect, including geometric structure, internal seepage and the composition of fine/coarse grained materials were analyzed.The advantages and disadvantages of this technique were pointed out.The main improvement measures and ways to enhance the protective performance of capillary barrier were discussed as well.The results show that capillary barrier technology is an important development direction of slop protection and ecological slop protection in the future.
