An earth and rockfill dam construction period flood season risk detection system and a detection method thereof

Abstract

The invention discloses an earth and rockfill dam construction period flood control risk detection system which comprises: an upstream flood level sampling module used for collecting upstream flood level data; The weir crest elevation calculation module used for calculating weir crest elevation data according to the upstream flood level data; The safety risk analysis module which is in communication connection with the upstream flood level sampling module and the weir crest elevation calculation module and is used for calculating the flood safety risk; The deterministic cost calculation modulewhich is used for calculating the cost required for heightening the cofferdam; The uncertain cost calculation module which is used for calculating the investment cost completed before the flood prevention cofferdam is heightened on the premise that a dam break accident occurs; The cost risk analysis module which is in communication connection with the deterministic cost calculation module and theuncertain cost calculation module and is used for calculating the flood cost risk; And the comprehensive analysis module which is in communication connection with the safety risk analysis module andthe cost risk analysis module and is used for calculating the flood risk of the construction period of the earth and rockfill dam. According to the invention, the flood risk detection accuracy of theearth and rockfill dam is improved.

Description

technical field [0001] The invention relates to the technical field of dam flood control, in particular to a flood risk detection system and a detection method during the construction period of an earth-rock dam. Background technique [0002] As a water-retaining structure to intercept rivers, raise water levels or form reservoirs, earth-rock dams have become the most widely used dam type in engineering because of their low cost, simple structure, and strong adaptability. However, due to the complex construction environment, the construction period is relatively long, and compared with the dam in the operation period, the functions of the earth-rock dam during the construction period have not yet been perfected, and various parameters have not yet met the design requirements, and the ability to resist floods during the flood season is even lower. , the earth-rockfill dam during the construction period has certain safety hazards and accident risks during the flood season. Th...

However, due to the complex construction environment, the construction period is relatively long, and compared with the dam in the operation period, the functions of the earth-rock dam during the construction period have not yet been perfected, and various parameters have not yet met the design requirements, and the ability to resist floods during the flood season is even lower. , the earth-rockfill dam during the construction period has certain safety hazards and accident risks during the flood season

The existing technology usually determines the risk probability based on the method of flood regulation calculation, and the risk probability detection is not accurate
