季节性气温变化对高速铁路桥梁沉降影响分析

Influence of Seasonal Temperature Changes on High-speed Railway Bridge Settlement

介绍了高速铁路工后沉降影响因素及工后沉降限值,通过实例分析了季节性气温变化对高速铁路工后沉降的影响。实验表明,季节性气温变化会导致高速铁路桥梁季节性的挠度变形,在高速铁路运营期沉降监测分析过程中应予以修正。

This article introduced the affective factors and maintenance settlement limitation of the high-speed railway. Through an example, the paper analyzed effects of seasonal temperature changes on the high-speed railway settlement during operation and maintenance. The example result shows that seasonal temperature changes can cause high-speed railway bridge seasonal deflection. This result should be considered in the high-speed railway settlement analyzing during operation and maintenance.
