Deformation of Water-Intake Head of Nuclear Power Plant Built on Soft-Soil Replaced Foundation
Based on Water-intake head of a nuclear power plant in China,a PLAXIS 3D finite element model is established to investigate the effect on structure displacement by adding pile foundation under water-intake head subject to soft soil replaced foundation with different sediment content.The analysis of the calculation results shows that the structure displacement tends to increase with the increment of sediment content in the soft soil replaced foundation.The structure displacement,especially vertical displacement significantly decreases by arranging pile foundation under the water-intake head.In addition,the change in sediment content has little effect on the structure displacement of soft soil replaced foundation,which effectively stabilizes the structure and ensures safe water-intake of the nuclear power plant.This research can provide a reference for the design of water-intake head structure of nuclear power plants under similar condition.
