| 摘 要： | 以包兰线框架墩为研究对象,分析基础刚度、墩身尺寸、跨径对框架墩温度内力的影响。通过对比分析得出基础刚度对框架墩温度内力影响最大,墩身尺寸和跨径对框架墩温度内力的影响也较大。设计时应尽量减小基础的刚度、墩身尺寸和跨径,以减小温度内力。

| Abstract: | This article analyzes the rigidity of foundation,the influence about the Span to the temperature force of frame piers by studying the frame piers of Bao Lanxian.Drawing the conclusion through the contrastive analysis,the rigidity of foundation is the biggest influence factor to the temperature force of frame piers;the size of pier body and the span have big influence to the temperature force of frame piers as well.We should reduce the rigidity of foundation、the size of pier body and the span in order to reduce the temperature force of frame piers in designing. |
