Embodiment Construction

[0026] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0027] Aiming at the problem that the bank collapse risk analysis method in the prior art is not accurate enough, the present invention proposes an idea of ​​analyzing the reservoir bank collapse risk based on the cloud theory. Cloud theory is a theory that combines fuzziness and randomness. It constructs a cloud generator to describe the uncertainty of concepts through expectation, entropy and hyperentropy, and can complete the transformation of qualitative concepts and quantitative values ​​simply and intuitively. Cloud theory fully reflects the randomness of evaluation while considering the fuzziness of concepts, and has certain advantages in dealing with inc...

Abstract

The invention relates to the technical field of reservoir dam collapse prediction, and discloses a reservoir dam collapse risk analysis method based on a cloud theory. The reservoir dam collapse risk analysis method comprises the steps of generating a cloud evaluation scale according to the digital characteristic of a risk grade evaluation theory domain; calculating the deviation degree of a cloud gravity center vector from an ideal-state cloud gravity center vector according to a decision matrix which reflects the comment of a decision maker to each risk factor; and determining the risk grade of dam collapse according to the deviation degree and the cloud evaluation scale. The reservoir dam collapse risk analysis method is combined with the field objective reality of the reservoir and can quantitatively evaluate the reservoir dam collapse risk. Furthermore the identified risk grade is more accurate.

Description

technical field [0001] The invention relates to the technical field of reservoir bank collapse prediction, in particular to a reservoir bank collapse risk analysis method based on cloud theory. Background technique [0002] With the acceleration of my country's economic construction, the demand for railway transportation is increasing, and the requirements for railway safety transportation are also getting higher and higher. For heavy-haul railways across the reservoir area, the safety of railway transportation must be fully considered, so the impact of reservoir collapse on the safe operation of railways has also become a key point that must be considered. [0003] The impoundment of the reservoir has caused major changes in the natural geological conditions of the river bank, and the water level in the reservoir area has risen to lift the erosion base level of the reservoir bank, causing major changes in the hydrological conditions of the river channel in the reservoir are...
