摘　　要：阐述了盾构隧道中心线产生偏移的原因,及隧道曲线的计算方法。顾及超高的影响,分别推导了隧道中心线在缓和曲线和圆曲线上的四种计算方法,结合上海轨道交通14号线的工程实例,验证了这几种计算方法是正确的,可以用于工程实践。最后,对这几种计算方法的适用范围给出了建议。The paper introduced the reason of offset of tunnel center line and the method of calculation on tunnel curve.Considering superelevation,four methods of calculation on transition curve and circular curve were derived.Those methods were proved to be right,combined with Shanghai Metro Line 14 engineering.At last,the scope of application of four methods was proposed.
