保龙高速公路植被护坡技术应用效果评价

Evaluation on Application of Bioengineering Techniques to Slope Protection of Baolong Highway

为研究高速公路植被护坡效果,依托保龙高速公路建设示范工程,遵循恢复生态学原理,对保龙高速公路边坡植被生长现状进行选样、调查、研究。结果表明:①植被物种的选择应以乡土植物为主,也可引入不具有强入侵性的外来物种;②植被护坡技术具有局限性,应与工程防护技术相结合;③对于较陡的岩质坡面可考虑在框格梁内设置种植槽,栽植攀援性和垂吊性植物。

To evaluate the protective effect of slope with vegetation and offer theoretical and technical references for the vegetation restoration and reconstruction of side slopes on Baoteng Highway,the ecological effect of re-vegetation on Baolong Highway side slope is studied.This study is based on the restoration ecological principles of Baolong Highway side slope construction project.The results show that： ①the selection of vegetation species should be focused on the native-based plant,and alien species with no strong invasive nature can also be selected;②bioengineering techniques for slope protection have limitations and should be combined with engineering techniques;③the relatively steep slope of rock could be considered to set planting trough within the box beam,planting climbers and hanging plants.
