摘　　要：植被防护和灰浆砌体防护是边坡坡面防护的常见形式,这里分别从力学效应和水文学效应方面比较分析他们的效能与局限性。植被护坡在改善生态环境方面的作用是显著的,但植被对坡体稳定性的影响却很复杂,积极与消极的作用共存。植被削弱雨水对边坡溅蚀、抑制水土流失的作用是显著的,并且对浅层土体也有加筋作用,但植被对边坡深层稳定的加固效应有明显的局限性,并有诱发深层滑坡的可能。灰浆砌体护坡对浅层土体没有加固作用,但能够防止水对边坡表面的冲蚀,把水挡在边坡之外,避免水分渗入坡体造成危害。Slope bioengineering and masonry structure engineering are the commonly used types for slope protection. Slope bioengineering has significant protective effect on ecology environment, yet vegetation has complex effect on the stability of slope, it plays both positive and negative roles. Masonry structure can inhibit the erosion of the slope caused by rainstorm, but it has not reinforcing function of the shallow soil. The impact principle of it is to keep the water from slope so as to avoid disaster. The inhibition of erosion provided by vegetation cover is remarkable, and it has reinforced action on the shallow soil. But the limitations of biotechnical slope protection is obvious, and it has the possibility to induce the deep seated landslide. This paper analyzed both effectiveness and shortcoming of bioengineering through mechanical effect and hydrological effect, and it may provide a good reference to find the ideal slope protection measures which can utilize the excellences for both bioengineering and masonry structure.
