任意点置镜测量既有曲线方法的研究

整正既有曲线是既有线提速改造和工务设计大修中的主要工作之一。传统的整正既有曲线的现场测量工作是将测量仪器置镜在曲线的钢轨上进行。这种方法既不安全 ,又容易引发交通事故 ,且工作效率极低。为改进传统的整正既有曲线的现场测量工作 ,满足火车提速和铁路建设的需要 ,提出采用置镜任意点的测量方法 ,对减少交通事故的发生和提高工作效率均具有十分重要的现实意义

Study on Survey Method for Existing Curve by Setting the Instrument at Any Proper Point

Adjusting the existing curvilinear railway is one of the major tasks in railway reconstruction for speed up of the train. In traditional site survey, the instrument is set on the curvilinear track. It is unsafe and very easy to cause traffic accidents resulted in a low efficiency. A new survey method by setting the instrument at any proper point is put forward, which could effectively decrease the occurrence of the traffic accidents and raise the efficiency of the engineering progress.
