| 英文摘要 | Debris flows are among the most common geological disasters in China, and have been particularly frequent in Sichuan Province since the Wenchuan earthquake on 12 May 2008. The construction of debris flow drainage channels is a countermeasure used to distribute debris flow fans, and these channels play a critical role in the mitigation and prevention of damage resulting from debris flows. Under field conditions, the useful life of drainage channels can be greatly shortened as a result of strong abrasions to the drainage structure caused by the debris flow. Field investigations have shown that the types of damage to drainage channels include (a) erosion caused by hyper-concentrated silt flow, (b) impact fractures and foundation scour at the ground-sills of the drainage channel, (c) destruction of the drainage channel outlet, and (d) destruction of the drainage channel caused by debris flow abrasion. In addition, based on the destruction of the drainage channel during the debris flow drainage process, a new type of drainage channel with energy dissipation components was proposed and applied in a steep, narrow gully for debris flow mitigation. Moreover, design and engineering repair recommendations for drainage channels are provided as a reference for repairing the damage to the channel. The results can provide an important reference for the effective repair and optimal design of drainage channels. |
