泥石流防治与景观融合性研究——以九寨沟县双柳地泥石流治理设计为例
Study on the fusion of debris flow control and landscape design: Taking the control design of debris flows in Shuangliudi, Jiuzhaigou County as an example
After the earthquake in Jiuzhaigou, a large number of rockfalls and landslides occurred in the afflicted area, providing a mass of source materials for the impending debris flows, which have become a potential threat to the safety and property of local residents. The study of control measures are required to prevent the recurrence of debris flows in Shuangliudi, Zhangzha Town, Jiuzhaigou County. Based on the concept of integral combination of control measures and landscape design, a new advanced technical method was adopted. Comprehensive prevention engineering designs, such as arc-shaped silting dam, sheet pile embankment, the decoration of the flood discharge trench, barrier at the bottom of flood discharge trench as well as greening were installed to separate rocks from water in the effluent of debris flows, which would in turn lower the possibility of an impending debris flow. This technical method is conducive to the control of debris flows with the integral combination of control engineering, surrounding environment and local culture.
