受台风“鲇鱼”影响,2016年浙江遂昌苏村山体滑坡,堵塞河流形成堰塞湖。堰塞湖抢险处置需要统筹快速解除溃决风险、搜救埋压人员等多项任务,是整个滑坡抢险救援行动的重点。根据山体滑坡抢险救援总体需求和堰塞湖抢险处置条件,提出“先北槽南降、再南槽北降”的“双槽”抢险处置方案,在实施过程中,根据抢险态势依时序分为“下槽截引”、“北槽南降”、“南槽北降”3个步骤。采用“双槽三步”方案快速解除了堰塞湖溃决风险,同时为搜救失联人员等创造了条件,圆满完成了堰塞湖抢险处置任务,也为类似堰塞湖抢险处置提供了成功案例。
Affected by the typhoon “catfish”, 2016 Suichang, Jiangsu Su village landslides, blocking the river to form a barrier lake. It is the focus of the whole landslide rescue and rescue operation that the dammed lake rescue and disposal needs to be co-ordinated to quickly relieve the risk of the collapse and search and rescue buried personnel and many other tasks. According to the overall demand of mountain landslide rescue and rescue and disposal conditions of dammed lake, proposed “double trough” rescue plan of “northward trough first and then south trough lower again”. According to the emergency situation, “Under the slot truncation”, “north slot down south”, “south slot north down” 3 steps. The “two-tank three-step” plan has quickly relieved the risk of the dammed lake ruin, and created the conditions for the search and rescue of the accidental detachment.
