摘要 该文对岩石边坡植被护坡工程原理及我国的技术现状进行了初步阐述,并为国内的岩石边坡植被护坡技术研究的发展方向提出了几点建议.岩石边坡植被护坡技术是指用活的植物与工程措施结合,以防止岩石坡面风化剥落的一项生态工程技术.岩石边坡植被护坡工程是在坡面构建各种各样的基质-植被综合保护体系,它可以看作是特殊的复合材料系统,基质-植被综合保护体系是岩石边坡植被护坡工程原理的重要组成部分,其护坡功能主要通过植被、引导基质与工程措施的协同作用来实现,可形成基岩-基质-植被的有机整体,达到稳固坡面的目的.岩石边坡植被护坡技术具有突出的优点和潜能,现已逐渐替代传统的护坡技术而成为岩石坡面防护的重要技术手段,其应用技术通常有框架内植草护坡,植被型生态混凝土护坡和厚层基材喷射护坡.同其他几类技术相比,厚层基材喷射护坡技术具有施工工艺简单、成本较低的优点,且其应用范围更加广阔,为我国岩石边坡植被护坡技术的发展起到了重要的促进作用. With the development of our country economic construction, the rocks slope was built increasingly based on fundamental construction to a large scope, which led to serious soil and water loss and ecological destruction. Therefore, the development and improvement of technique to stabilize rock slope with vegetative is significant to the building of ecological environment of our country. This paper summarized the developing trend and situations of technique to stabilize rock slope with vegetative in China, and provided some suggestions for this technique to develop in future.The engineering of stabilizing rock slope with vegetative are various 'base matter'-plant comprehensive protection system built in rock slope. Considering its protection function of protecting the whole rock slope, it can be thought particular combined material system. 'Base matter'-plant comprehensive protection system was an important part of engineer principle of vegetative cover of rocks slope. The technique of stabilizing rock slope with vegetative cover increases the adhering power of 'base matter' by roots of plants, furthermore, connects the 'base matter' with rock together to form an organic integrity, thus will stabilize the rock slope.The technique usually includes:planting grass in framework, ecologic 'concrete' with vegetative cover, and thick-layer base material spraying.Compared with another technique, thick-layer base material spraying characters with being easy to build, low cost, and easy to maintenance after being built, thus its application is extensive in China. So, thick-layer base material spraying takes an important role for technique to stabilize rock slope.On the whole, vegetative cover technology was in a primary stage. People thought it as an application technology and their learning about it was restricted in qualitative and experimental period. There exists many problems, such as simple vegetative combination, poor adaptability, high engineer cost and difficult management, which inhibited the popularization of the t
