| 摘 要： | 生态防护是目前城市道路和高速公路岩质边坡生态加固的一项主要措施。生态防护对边坡的防护方面是多方面的,分析了植物根系与边坡的力学效应,探讨植物根系加固边坡作用机理,提出根系—土复合层增加抗剪强度公式。此外,本文研究了植物根系对边坡降雨截留、径流延滞、土壤防渗、土层固结等效应,初步探讨了生态防护对边坡的抗冲刷机理。工程实践表明生态防护边坡具有较好的生态效应和社会效应。

| Abstract: | Bio-engineering protection is one of methods to treat urban highway and expressway at present.Bio-engineering protection has multi-functions protection to rock slope.The mechanic effect of bio-engineering to rock slope was analyzed and the mechanic of roots of plant to rock slope was investigated,putting forward to a formula of increasing anti-shear strength of root-soil layer.Meanwhile,the effects of bio-engineering such as rainfall interception,runoff put-off,anti-seepage of soil,etc.were studied,discussing the mechanic of anti-washout.Practice showed that bio-engineering protection of rock slope is of better biologic effect and social effect. |
