Problems solved by technology

[0003] Most of the existing safety assessment methods for hydraulic tunnels are mainly based on the assessment of water conservancy project equipment, geological environment conditions of hydraulic tunnels, or defect characteristics of hydraulic tunnels. It is often difficult to give the specific location of hydraulic tunnel risks, which reduces the safety assessment. Accuracy, also increases the cost of hydraulic tunnel repair

Abstract

The invention discloses a hydraulic tunnel risk assessment method and device and a terminal device. The method comprises: acquiring hydraulics data and inspection image parameters of different positions of a hydraulic tunnel; establishing a three-dimensional model of the hydraulic tunnel, and performing fluid simulation on the hydraulics data in the three-dimensional model to obtain hydraulics characteristic distribution information; performing feature extraction on the inspection image parameters through image recognition to obtain feature data of each defect; conducting stress analysis according to the hydraulics characteristic distribution information, and obtaining the pressure value of the corresponding position of the hydraulic tunnel according to the analysis result; and taking thehydraulics characteristic distribution information and the defect characteristic data as evaluation characteristics, and performing weighted fusion through a hydraulics evaluation model to obtain a risk evaluation value of a corresponding position. According to the technical scheme, hydraulics data are introduced on the basis of defect characteristic data, hydrogeological conditions of the hydraulic tunnel are better described, evaluation accuracy is higher, and feasibility is higher.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a risk assessment method, device and terminal equipment for hydraulic tunnels. Background technique [0002] The geological conditions and construction technology of hydraulic tunnels are complex, and the understanding of geological conditions during design is not yet comprehensive and accurate. Due to the aging of hydraulic tunnels, cost, management and other reasons, the problem of hydraulic tunnel diseases is more prominent. As one of the important components in the hub, the hydraulic tunnel line must be compatible with the construction tasks of the hydraulic hub. [0003] Most of the existing safety assessment methods for hydraulic tunnels are mainly based on the assessment of water conservancy project equipment, geological environment conditions of hydraulic tunnels, or defect characteristics of hydraulic tunnels. It is often difficult to...
