铜汤高速路堑边坡生态防护工程技术探讨

Studies on Ecological Protection Engineering Technology for Cutting Slope of Tong-tang Highway

以铜汤高速公路为例,通过对沿线植被、土壤质地等立地条件的调查,结合生态恢复因子,通过工程实践对本段高速公路路堑边坡的生态恢复工程技术进行了探讨.根据植物种类选择的原则,选取了乔木类、灌木类、草本类植物进行边坡生态绿化,并提出了客土喷播技术、厚层基材喷射技术等具体边坡生态防护施工技术,指出了当前技术的绿化效果及存在的问题,为铜汤高速路堑边坡生态防护工程建设提供了详细方案.
