To analyse the solar temperature field and deformation of ultra-high hollow thin-walled piers, based on the 192 m thin-walled hollow piers of Lugou River Bridge in Chongqing, China, the two most unfavourable temperature fields of high temperature in summer and low temperature in winter are selected. The variation rule of wall temperature and displacement of piers under the action of solar radiation is studied using finite element software ANSYS, and the influence of cross-sectional changes of piers on the displacement of pier tops is analysed in detail. The results indicate that the finite element solution in this paper is in good agreement with the literature solution, which verifies the reliability of the finite element analysis in this paper. The temperature change of the east and west pier walls is the most significant in the high temperature environment in summer, and the temperature change of the south pier wall is more obvious in the low temperature environment in winter. The deformation of the pier in winter is significantly greater than that in summer under the action of sunlight. When the volume of the pier remains unchanged, the displacement of the octagonal section pier is close to that of the rectangular section pier. Due to the increase in cross-sectional stiffness, the round-end pier can effectively reduce the displacement of the pier body caused by sunlight.References
