Seismic Analysis of Inlet and Outlet of Water Intake Channel

Abstract

Aiming at the nuclear power plant structure of Haiyang Shandong and adopting time domain analysis approach, the seismic analysis of inlet and outlet parts of water intake channel are made in this paper. The changes of internal force of the inlet and outlet parts of the water intake channels under the complicated muti-load environment of soil pressure, temperature, water hammer pressure, seismic load is analyzed. The calculation results show that the water hammer pressure, the seismic load and wall thickness of the wall have a significant effect, and encrypted reinforcement at the weak section should be applied during the design and construction. The calculation can provide the basis for the seismic analysis of the water intake channel in nuclear power plant.
