ABSTRACT OF THE DISCLOSURE A method for regulating and controlling discharge flow of a dammed lake includes steps of: (S1) estimating a most dangerous discharge condition; (S2) based on the most dangerous discharge condition, calculating a structural internal force of the steel flexible net; (S3) based on the internal force of the steel flexible net, calculating an anti-slide embedded depth at two sides of the steel flexible net; (S4) based on the most dangerous discharge condition, manually excavating a channel; and (S5) based on the anti-slide embedded depth at the two sides of the steel flexible net, embedding the steel flexible net into a barrier dam. According to the present invention, the steel flexible net is laid on the upstream slope of the barrier dam, two sides of the steel flexible net is embedded into the slope body with gravels of the barrier dam, and cooperates with the channel for usage.

Method for regulating and controlling discharge flow of dammed lake

A flexible barrier includes: posts, retaining ropes and a metal net; wherein each of the posts comprises a post body and a post foundation hinged; the retaining ropes includes longitudinal retaining ropes, top retaining ropes, intermediate retaining ropes, and diagonal retaining ropes connected between the posts and the metal net; wherein a lower portion of the metal net is obliquely arranged towards a downstream of a slope; the metal net is loose when no impact is applied and a bottom of the metal net is fixed with short anchors; the bottom of the metal net has a redundancy and is folded towards a upstream of the slope or buried in the slope.
