The annual variation of temperature will cause the uniform change of temperature in the structure,which will cause the deformation and internal force in the structure,and the effect of temperature will often cause adverse influence in high-piled wharf projects.In order to analyze the temperature effect of beamless-slab high-piled wharf,on account of the heat conduction law of infinite slab,we establish the finite mesh model with ABAQUS based on the real engineering projects.Based on the hourly meteorological data in Hangzhou,the variation characteristics of temperature,the temperature difference field of slab,the structural deformation and displacement were studied,and the selection of basic temperature was discussed.The results show that air temperature presents one-dimensional heat transfer characteristics mainly in thickness direction in beamless slab and temperature field is uniformly distributed in horizontal direction.The annual variation of air temperature hardly attenuates in the panel,and the influence of daily variation on the panel temperature can not be neglected.Temperature response of foundation piles of beamless-slab wharf is controlled by the overall temperature difference of the slab,and the two changes are simultaneous.
