摘要
通过分析冲沟泥沙流灾害的主要诱发因素、形成机制和演化规律,提出上拦、下排、中间削坡绿化的综合治理方案,采用加筋土护坡控制住沟头侵蚀,冲沟出口采用加筋土拦沙坝实现泥沙与水分离,降低营运阶段养护成本。该治理技术在广佛肇高速花岗岩水土流失区已成功应用,可供类似泥沙流灾害工程参考。
The comprehensive treatment schemes for greening of cut slopes at upper column, lower row and middle are put forward by analyzing main inducing factors, formation mechanism and evolution law of mud - sand flow disaster of gully, the reinforced soil slope protection is adopted to control the gully head erosion, and the reinforced soil debris dam is adopted for gully exit to realize the separation of mud sand and water and reduce the maintenance cost of operation stage. The control technology has been successfully applied in water and soil loss area of granite on Guangzhou - Foshan - Zhaoqing Expressway, so as to provide reference for similar mud - sand flow disaster engineering.
