保龙高速公路植被护坡技术应用效果评价

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。

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

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.
