摘要
客运专线铁路建设标准高,技术要求非常高,必须满足高速度、高密度、高舒适性和高安全的要求,而其线下工程沉降变形观测评估是我国高速铁路建设中一个特有的技术环节,缺乏可资借鉴的经验,亟需研究。介绍客运专线铁路沉降评估的一些基本概念、双曲线及指数曲线理论及2种方法在高铁沉降分析中的应用,通过实例计算,证实指数曲线法得到的结果略优于双曲线法。
High-speed railway features high construction standard,high technology,high train speeds,high transportation density,high amenity and high safety,and the observation and evaluation of line settlements constitute a specifical technical process in constructing high-speed railways in China.Up to now there is no referential experience and it has to be studied immediately.This paper introduces some basic concepts of evaluating settlements including the theory of hyperbolic and exponential curves and the application of this two methods for high-speed railways.It has been shown that for settlement analysis the exponential curve method can obtain better results through examples of calculation.
