山区高速公路边坡防护的新型技术——植物草毯生态防护技术

A New Slope Protection Technology for Expressway in Mountainous Area——Vegetation Grass Blanket Bioengineering Technique

通过对比,分析了典型的人工植被、三维植被防护、客土喷播、网袋工程等边坡生态防护技术特点和适用范围。重点介绍一种新型山区高速公路边坡生态防护技术——植被毯技术,阐述了植被毯生态防护技术的防护原理。结合六潜高速公路植被毯边坡防护工程实例,分析了这种防护措施的可行性,对其生物防护的机理、特点、设计原则、施工工艺进行探讨。为山区高速公路边坡的生态防护,尤其是劣性土质和岩质边坡生态防护提供了重要参考。

The advantages and protection mechanism of tainous area expressway are analysed. The typical slope bioengineering technique for slope protection in mounbioengineering technology characteristic and applicable scope are illustrated ,such as laying turf, three-dimensional vegetation protection ,soil spray-sowing, net engineering. A new bioengineering technique is presented ,which is the vegetation blanket for slope protection in expressway,and its principle,characteristic,design method and craftwork are discussed with an experiment in the expressway from Lu＇an to Qianshan. It provides important reference for mountainous expressway slope,especially for the poor soil and rock slope ecological protection.
