生态型柔性边坡护坡各类工程技术特点与前景展望

Various Engineering Technical Characteristics of Ecological Flexible Side Slope Protection and Foreground Expectation

柔性护坡是利用植被等涵水固土的原理稳定岩土边坡,同时美化生态环境的一种新技术,是涉及岩土工程、修复生态学、植物学、土壤肥料学和土工材料等多学科于一体的综合工程技术。随着我国经济建设的蓬勃发展,工程技术日益提升。然而,工程建设往往会破坏生态环境,其建设开挖和填筑都会导致原生植被和动物栖息地破坏,水土流失,以及局部环境恶化等一系列生态环境问题,工程建设与环境保护的矛盾日益突出。因此,恢复和重建工程护坡及工程周边的自然生态植被尤为重要。该文通过对近十多年来的柔性护坡新技术进行总结与探讨,论述了柔性护坡的功能、技术特点与施工方法。技术的推广既能起到良好的边坡防护作用,降低造价,又能改善工程环境、体现自然生态环境美,使生态平衡可持续发展。

The flexible slop protection is a new technique to use the water and soil conservation principle of the vegetation to stabilize the rock side slope and at same time to beautify the ecological environment,and is the integrated engineering technique related to many subjects of the geotechnical engineering,recovery ecology,botany,soil fertilizer and civil engineering material.With the flourishing development of the economical construction in China,the engineering technologies are increasingly advanced.However,the engineering construction destroys the ecological environment sometimes.The construction excavation and filling all result in a series of ecological environmental problems of destroying of original vegetation and animal habitat,water loss and soil erosion,the partial environmental worsening,and increasingly extruding contradiction between the engineering construction and the environmental protection.Therefore,it is more important to recover and rebuild the engineering side slope and the natural ecological vegetation surrounding the projects.The article sums up and probes into the new technique of the flexible slop protection of more than 10 years,and discusses the function,technical characteristics and construction method of the flexible slop protection. The technical popularization not only plays the good role of side slop protection and reduces the construction cost,but also improves the engineering environment and embodies the beautiful natural ecological environment to make the ecological balance and sustainable development.
