Embodiment Construction

[0048] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar extensions without violating the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0049] Please see figure 1 , figure 1 A schematic diagram of the composition of a dam system failure flood analysis system provided in this application.

[0050] The dam system failure flood analysis system includes: a dam system topology analysis module, a data collection module, a single dam analysis module, a flood evolution analysis module, and a dam system analysis and prediction module.

[0051] The topology analysis module of the dam system is used to determine the classification of each dam in the dam system accor...

Abstract

The application discloses a dam system failure flood analysis system, including: a dam system topology analysis module, a data collection module, a single dam analysis module, a flood evolution analysis module and a prediction module; the dam system topology analysis module is used for Determine the classification of the dams in the dam system; the data collection module is used to collect the information of the dams in the dam system; the analysis module of the single dam is used to establish the water level model of the dam, according to the water level model of the dam and the building parameters of the dam body The data determines the flood state model of the dam; the flood evolution analysis module is used to analyze the process of flood flowing from the low-grade dam to the high-grade dam, and calculates the inflow of the downstream high-grade dam according to the outflow of the low-grade dam; The prediction module is used to predict whether the downstream dam will fail if the dam fails during the flood evolution process, predict the failure time of the downstream dam failure, and the peak flow of the failure flood.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201810253242.X and the title of the invention "Methods for Safety Assessment of Dam Systems" submitted to the China Patent Office on March 26, 2018, the entire contents of which are incorporated in this application by reference middle. technical field [0002] The invention relates to the technical field of water conservancy engineering, in particular to a dam break flood analysis system and method of a dam system. Background technique [0003] In larger watersheds with complex topography, dams for water retention are distributed along the river course. The combination of the aforementioned multiple dams is called a dam system. [0004] When the precipitation in the basin is small, the adjustment and storage capacity of each dam can cope with the confluence of the inter-basin and the discharge of the upstream reservoir, and there will be no problem of dam failure.
