Description

technical field [0001] The invention relates to the field of anti-seismic technology of hydraulic engineering, in particular to a coupling system and synthesis method of ground motion and water flow excitation of a hydraulic gate. Background technique [0002] The number of sluices in the diversion project from the Han to the Wei River is large, the scale is large, the service environment is complex, and the key technologies are difficult. Especially under the coupling of various random factors such as strong earthquakes, water flow, and environmental excitations, complex dynamic responses will be generated. The safe operation of the structure poses a serious threat. In water conservancy and hydropower project hubs, if the sluice and the associated drainage facilities are damaged by an earthquake, the water level of the reservoir will rise, which will threaten the safety of the dam. In addition, earthquake damage to large-scale power facilities will lead to interruption of ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a coupling system and synthesis method for ground motion and water flow excitation of hydraulic gates, because the existing methods cannot reasonably, accurately and efficiently analyze the seismic-water flow coupling dynamic response for gates and hoisting facilities. The law and failure mechanism of the seismic-water flow coupling dynamic response of gates and hoisting facilities cannot be obtained, so that data and technical support cannot be provided for the gates to improve their seismic resistance and water impact resistance
