A gradual densification node-based control and guidance engineering layout method for wandering rivers

Abstract

The invention discloses a gradually-densified node type river control work arrangement method for a wandering river channel. The method comprises the following steps of determining of inherent nodes of the river channel in the wandering river channel; arrangement of first nodes; evaluation of arrangement effect of the first nodes; arrangement of second nodes, and subsequent adjusting, wherein the first nodes and the second nodes respectively adopt a series of discontinuous regulation buildings, the interval distance is determined according to the wandering property, and the nodes are gradually densified according to the primary regulation effect so as to enhance the constraint of the river channel, namely that the regulation building (namely the second node) is built continuously between the two first nodes to increase the number of nodes; the variable-density node arrangement type can be adopted according to the wandering change of different river reaches. The method has the advantages that the engineering quantity is obviously reduced, the buildings can be gradually built by phases, and the one-time fund investment is less; according to the characteristics of the river channel, the river control work can be arranged according to local conditions; according to the previous regulation effect, the work arrangement can be adjusted.

Description

technical field [0001] The invention relates to a water conservancy project river regulation technology method, in particular to a progressively dense node-type control and guidance project layout method for wandering river courses. Background technique [0002] The mainstream of wandering rivers fluctuates, and the rivers change drastically. In order to improve the boundary conditions of the river, restrict the swing range of the mainstream, adjust and stabilize the position of the mainstream, it is necessary to regulate the wandering river and build river regulation structures. Common forms of river regulation structures include spur dikes and bank revetments. The layout of the remediation buildings is mainly based on the remediation line, and the remediation buildings in the long river section are built along the river bank to form continuous linear buildings. [0003] There are the following problems in the layout of traditional river regulation projects: 1. The amount...

AI Technical Summary

Problems solved by technology

[0003] There are the following problems in the layout of traditional river regulation projects: 1. The amount of regulation projects for long rivers is large, and more resources are invested at one time; The remediation measures cause waste of resources; 3. After the remediation project is completed, it cannot be changed, and the remediation plan cannot be adjusted according to the preliminary remediation effect
