浅谈京石高速铁路工程的测绘工作

Surveying and Mapping work of Jingshi High Speed Railway

高速铁路是指通过改造原有线路(直线化、轨距标准化),使营运速率达到每小时200公里以上,或者专门修建新的"高速新线",使营运速率达到每小时250公里以上的铁路系统。"十二五"期间,我国大力加强高速铁路交通的建设力度,使得高速铁路在国民经济建设中的地位日益增加。结合近几年承接的高速铁路轨道交通的测绘工作,以京石高速铁路北京段14～48千米拨地的实际工作情况来谈谈在建设高速铁路过程中的测绘工作的应用,简单介绍作业方法、基本流程、质量控制措施以及经验和心得体会。

High speed railway is defined through the transformation of the original line （ straight hne, gauge standard）, so that the operating speed of 200 kilometers per hour or more, or specially built new ＂freeway＂, so that the operating speed of 250 kilometers per hour above the rail system. ＂Twelfth Five-Year Plan＂ period, our country strengthen high-speed railway traffic construction, high-speed railway construction in the national economy status is increasing. Combined with the recent years to undertake high speed railway track traffic survey and mapping work, with Jingshi high speed rail- road Beijing 14 to 48 km for the BoDi work to talk about in high speed railway construction in the process of the work of Surveying and mapping application, introduces tb.e working method, basic procedure, quality control measures and experi-ence and experience.
