摘要
高速铁路是指列车运行速度２００ｋｍ／ｈ以上的铁路，我国对既有铁路进行提速改造的同时，拟修建京沪高速铁路，全长１３０７ｋｍ，时速２５０ｋｍ。高速铁路技术要求比普通铁路显著提高，在高速铁路勘测工作中，平面和高程控制是高速铁路建设成功的首要条件。本文对高速铁路的平面和高程控制精度进行了论证和推导，以期为我国高速铁路勘测、设计、施工、维修提供理论上的依据。
The train operating speed in high speed railway is usually over 200 km/h.While raising speed on existing railways in China,the Jing Hu High Speed Railway will be constructed with running speed of 250km/h and having a total length of 1307m.The technical requirements for high speed railways are much higher than that for ordinary railways.In the surveying works for the high speed railways,the plane survey and the vertical control are of the first importance for successful construction of a high speed railway.The paper infers and demonstrates an accuracy issue for plane survey and vertical control of high speed railway,for the purpose of offering a theoretical basis for survey,design,construction and maintenance of our national high speed railway.
