Abstract
The invention discloses a debris-flow prevention method by controlling debris-flow magnitude and avoiding to block main river. This method first adopts the drainage works for delivering debris flow in corporation with the transport of the main river; if the drained sediment cannot be transported by the main river, the blocking works are adopted; and if the sediment still exceeds the delivering capacity, the deposit stopping works are adopted. Compared with the prior art, this invention makes full use of the main river's transport capacity, gives priority to dredging and also reasonably distributes the sediment and deploys the engineering system, so as to realize the safe discharge of debris flow, and avoid the secondary disaster of 'barrier lake' caused by the blocking of main river due to excessive discharge of debris flow and fully guarantee the safety of mountain towns, major projects and infrastructure located at the mouth of debris flow gully.
