摘要

公路边坡是公路建设中破坏最为严重的区域之一。根据在陕西省西安市至安康市高速公路进行的试验研究

总结出了护面墙、框格防护、铺砌片石护坡、排水固结等19种边坡防护形式。施工中应根据具体的工程特点确定合适的防护方式。在该段高速公路具有代表性边坡和二级边坡设定了22个监测点

以观测包括灌木的干茎、冠径、高度的变化

草坪的覆盖度、成活率、出苗率、生长势等项目

并且分析了植被生长情况与环境条件的关系。研究结果可为高速公路边坡绿化模式的选择提供参考。

Abstract

Highway side-slope is one of the most seriously damaged areas in highway construction. Based on an experimental study in the Xi′an-Ankang highway of Shaanxi Province

19 side-slope protection forms are summarized and analyzed

i. e.

retaining wall

gridiron protection

paved stone slope

drainage consolidation

etc. . 22 scientific research sites were set on tipical slopes and secondary slopes in the Xi′an-Ankang section to observe the changes of shrub stem

diameter and height

lawn coverage

survival rate

emergence rate and growth potential

as well as to analyze the relationship between vegetation growth and environmen-tal conditions. It is clarified that a suitable protection form should be determined by the characteristics of specific engineering. The result from the analysis can offer scientific reference for selecting an ecological sideslope protection mode in highway construction.
