| 摘 要： | 讨论了现有温度配筋方法的不足，采用钢筋混凝土非线性有限元方法，根据使用阶段最大允许裂缝宽度来合理配置的温度钢筋；并运用这一概念对三峡升船机塔柱筒体结构的温度配筋进行研究，分析了配筋量与裂缝开展、裂缝宽度之间的关系，确定了合理的温度钢筋用量，和现有的方法进行了对比。

| Abstract: | The demenitsy of existing temperature reinforcement design methods are discussed,
and a reasonable method in which the temperature reinforcement is determined by RC nonlinear
finite element method according to the maximum permissible crack width is presented. It is
introduced to determine the temperature reinforcement of tube-structure of the ship lift in the
Three Gorges Project. The relationship between the quantity of reinforcement and width of crack
is analysed, and the reasonable quantity of temperature reinforcement is suggested. |

| Keywords: | reinforced concrete nonlinear finite element method temperature reinforcement crack width tube structure ship lift |
