高速公路护坡草坪草种的气候分区和选配组合技术研究

中国高速公路已经建成6.5万多km,边坡生态恢复问题近年来被广泛关注,高速公路的边坡占总绿化的70%以上,其生态恢复成为高速公路景观设计的重点,它涉及到生态补偿、景观水平、地方文化等诸多领域。笔者根据中国各地的气候和土壤特点,将全国分成7个气候区,并将中国高速公路的边坡草坪草种按生态适应能力进行排序,提出对应各个区的草种组合方案和使用原则,为各地高速公路边坡草坪草种的选择提供理论依据。

Stability evaluation and protection of slope for Laosongling-Yanji Highway

The authors analyzed the engineering geological characteristics of the slope of the study area (K75+840-K76+340). Two typical cross-sections have been chosen to analyze the failure modes after the excavation of the highway. Different types of the failure modes have been calculated and analyzed. The results show that some dealing methods have been advised to ensure the stability of the slopes.
