    香根草护坡机理的初步试验研究

    PRELIMMINARY EXPERIMENT STUDY OF SLOPE PROTECTION MECHANISM USE VITIVER

    • 摘要: 生态护坡与植物护坡是边坡防护与加固方案和技术发展的重要领域,香根草是一种易裁种快长的禾木科草本植物,具有强盛的根系网络系统,具有加固和防护边坡的良好功能。试验表明,香根草根系的抗拉强度较大,而且随根数(集群度)成线性增大,随根系的长度的增大而略有减小。均匀拌入香根草根系的砂质粘土的物理和力学特性有显著的变化,即土的容重变小而土的抗剪强度则有明显的增大。它反映了种植香根草的边坡的稳定性得以提高是必然的结果。

       

      Abstract: Slope protection with ecology and plants has become an important field in methods and techniques of protecting and stabilizing slopes. Vitiver is a kind of easilily rooted and rapidly grown gramineous grasses, which has the powerful root's system and the first-class capability to protect and stabilize slopes. Experiments have shown that not only vitiver's root system has the relatively high tensile strength, but also the strength linearly increases or decreases when the number of its roots (density of root distribution) ecomes ;But the strength will sightly decrease with the increasingly long roots . Physical and mechanical properities of sandy clay evenly mixed with vitiver's root system obviously become, that is to say, the soil's unit weight reduces and its shear strength has an visible increase. This fact proves that slope's stability being improved is inevitable when there exists vitiver in the slope.
