Method and device for calculating height of side wall of abrupt slope channel

Abstract

The invention discloses a method for calculating the height of a side wall of an abrupt slope channel. The method comprises the following steps: calculating the water depth h0 of clear water in the abrupt slope channel; calculating the aerated water depth ha in the abrupt slope channel; and determining the height h of the side wall according to the position of the aeration point, the clear water depth h0 and the aeration water depth ha. The invention further discloses a device for calculating the height of the side wall of the abrupt slope channel. The side wall height of the abrupt slope channel obtained through the method for calculating the side wall height of the abrupt slope channel is more reasonable, and materials of the drainage channel side wall can be saved.

Description

technical field

[0001] The invention specifically relates to a calculation method and a calculation device for the height of the side wall of a steep slope channel. Background technique

[0002] The design of drainage channels in mountainous and hilly areas, such as the height of channel side walls, needs to consider the hydraulic characteristics of steep slope rapids. In the prior art, the height of steep channel side walls is usually set to the sum of clear water depth, aerated water depth and safety superelevation , the steep channel margin obtained by this calculation method is too large. At the same time, the height of the steep channel side wall designed in the prior art is not designed according to the position of the aeration point. The height of the steep channel side wall before and after the aeration point is All the same, waste building materials, increase the manufacturing cost of engineering. Contents of the invention
