Problems solved by technology

Among them, the grid method, section method, and contour line method need to manually set the grid and section positions, and the disconnection of the terrain contour line is also a cumbersome process. The DEM method is based on the DEM data provided by the surveying and mapping profession, and simulates the real terrain. There are some deficiencies in aspects, these problems make it difficult to meet the engineering requirements in terms of the efficiency and accuracy of calculating the static storage capacity of the reservoir

Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and implementation examples.

[0025] The first step is to obtain the XYZ coordinate data of terrain points and save the obtained data as "terrain.txt" in the following format;

[0026]

[0027] The second step is to import the "terrain.txt" file saved in the first step into the Gocad platform;

[0028] The third step is to use the DSI interpolation technology to construct the topographic surface under the Gocad platform, and perform multiple DSI interpolation fittings on the constructed topographic surface, so that the topographic surface is infinitely close to the real topographic surface (GCD-1000), and at the same time generate the topographic surface Outer boundary lines (contour lines), such as figure 1 shown;

[0029] The fourth step is to use IDL language to design an automatic calculation program. The storage capacity at a certain ...

Abstract

The invention discloses a method for quickly calculating the static storage capacity of a reservoir based on a DSI technology. The method comprises the steps that first, a topographic surface which is infinitely close to the real is established; second, a program which can automatically calculate the area and the storage capacity of the reservoir is programmed; third, an area and storage capacity variation curve is automatically calculated and drawn. According to the method for quickly calculating the static storage capacity of the reservoir based on the DSI technology, the speed and the accuracy of calculating the static storage capacity of the reservoir can be improved, the storage capacity calculating is made to be not influenced by the types of the topographic surfaces, the time for calculating the storage capacity of the reservoir is greatly shortened, the advantages of being high in efficiency, high in speed and capable of automatically outputting calculating charts and tables are achieved, and a wide application prospect in the filed of calculating of the static storage capacity of the reservoir is achieved.

Description

technical field [0001] The invention relates to the determination of specialized storage capacity of hydrology and water energy in hydropower and water conservancy projects, in particular to a fast calculation method for static storage capacity of reservoirs based on DSI technology. Background technique [0002] Accurate reservoir static storage capacity and its change curve are the basic data for lake, reservoir management, and water conservancy and hydropower engineering planning and design, which are used to maximize the use of water resources, effectively carry out flood control and operation management, and confirm the type of reservoir. [0003] The methods currently used to calculate the static storage capacity of reservoirs include grid method, cross-section method, contour method, DEM method, etc. The basic principles of these methods are all formed by cutting, dividing and summing according to the method of calculus . Among them, the grid method, section method, a...
