摘　　要：用热弹性理论分析了混凝土圆形空心墩的日照温度效应问题,推导出了圆形空心墩温度应力分布的弹性理论解,并提出了墩顶温度位移的计算公式。所得理论解比传统计算方法精度更高,计算更简便。By means of the theory of thermoelasticity, the sunshine thermal effect problem of cylindrical concrete hollow pier is analyzed, the elasticity theoretical solutions to the thermal stress distribution of the pier are derived, and corresponding formulae for calculating the pier top thermal displacement are developed. Compared to the conventional calculation methods, the solutions developed in the paper are more precise, and simpler and easier for calculation.
