摘要
临沧地区广布风化混合花岗岩边坡,高速公路建设中形成的边坡植被恢复困难,坡面冲刷破坏严重。对墨临高速公路数十个边坡的植被恢复和冲刷破坏情况开展了现场调查分析,以两个典型的高边坡和中低边坡为例,介绍了不同坡高边坡的植被恢复和冲刷破坏情况。根据调查结果,总结了影响混合花岗岩边坡坡面冲刷破坏的主要内因和外因,针对不同混合花岗岩边坡和不同部位,提出了合理的植被恢复方法,可有效防止坡面冲刷破坏,通过工程实例验证了植被恢复方法的有效性。
The weathered migmatitic granite slopes are widely distributed in Lincang area.It is difficult to restore vegetations after the slope excavation for the expressway construction.The resultant erosion hazards consequences are serious.The field investigation and analysis of the vegetation restoration and erosion control of dozens of slopes of Mo-Lin Highway are presented in this paper.The vegetation restoration and erosion control conditions of two typical slopes with one high slope and the other medium-low slope are investigated,evaluated and the results are introduced in the paper.The main internal and external factors affecting the slope erosion of the migmatitic granite slope are summarized in accordance with the field investigation results.For the different types of migmatitic granite slopes and different locations on the slopes,reasonable vegetation restoration methods are proposed,which can effectively minimize the slope erosion hazard.The effectiveness of the vegetation restoration method is verified by an engineering slope case istory.
