三维网植被护坡技术在广巴高速公路的运用和改良

本文论述了三维网植被技术在广巴高速公路上的运用和改良,针对适用边坡坡度等方面的问题提出见解.该技术适用坡比1:1的土质路堑边坡和坡比不陡于1:1的泥岩及砂泥岩互层路堑边坡;在实施过程中应选择EM4型三维网并充分重视其养护;网下覆盖耕植地表土后挂网种植相关植物;前期以草坪草防护为主、后期再行灌木防护;灌木品种选择适应性强、较耐干旱、瘠薄的物种和当地的土著树种.

The Utilize and Improvement of the Technology of Three-dimension Vegetative Net on Slope Protection in the Guangba Highway

This article reported the utilize and improvement of the technology of three-dimension vegetative net on slope protection in the Guangba highway. The author proposed somes suggestions such as suitable for the slope and other problems. The technique was applicable to the soil cut slope which the slope ratio was 1 ： 1 and the shale and sand mudstone slope which slope ratio was more than 1： 1. The author advise that EM4 three-dimension vegetative net would be chose and maintained fully. Before planting the surface part of the planting soil should be covered under the net. Lawn grass protected the slope mainly in the prophase. And in the later period it was mainly the shrub. The shrub plants should be strong adaptable species, more resistant to drought and barren species or native species.
