高铁无砟轨道基准点平面测量方法

摘要

介绍一种在狭长测量条件下基于边角后方交会自由设站的测量方法,阐述方法的原理,并结合石武高铁CRTSⅡ型板式无砟轨道基准点平面测量的具体实例应用,分析该测量方法的精度,证明该方法在狭长呈带状、要求越来越高的测量环境中应用的可行性和可靠性,对其他大型精密工程测量具有参考价值.%Measure based on edge horn resection under the condition free of measuring method of setting up station in a long and narrow condition is discussed. The paper expounds the principle of method, and combined with Shiwugao iron CRTS Ⅱ type plate frantic jumble no track the specific example base plane measurement, and analyzes the application of the method of measuring precision, proves the method's feasibility of application and reliability in the long and narrow band, the request of measurement environment is more and more high. It has practical reference value for other large, precision engineering measurement.
