【摘要】 为提高当前既有普通铁路运营维护施测的数据精度、作业安全系数与工作效率,对既有施测工法采用的测量工具、具体实施方案以及数据处理等方面进行了深入分析与研究,将自由测站法引入到既有铁路曲线平面测量作业中,并有针对性地进行了测量工具的设计与改进,以及大量不同曲线条件下施测方法的实验和数据处理结果的对比等工作,进而提出一套铁路曲线测量新工法。现场施测作业的反馈和实践证明,该方法将里程丈量精度由厘米级提升至毫米级,提高了测点定位精度;现场测量仪器无需频繁搬站上下线路,提高了作业安全系数和现场施测的工作效率;有针对性地开发了数据处理程序,可精准对接外业数据,提高了数据处理效率。更多还原

【Abstract】 In order to improve the data accuracy,operation safety factor and work efficiency of the operation and maintenance survey for existing general railway,this paper makes a thorough analysis and study on the measurement tools,concrete implementation scheme and data processing of the existing survey method,introduces the free station method into the existing railway curve plane survey operation and puts forward a new method of railway curve measurement after carrying out the design and improvement of the measuring tools,and the comparison between a large number of experiments and data processing results under different curve conditions. Feedback and practice of field survey operation prove that this method improves the accuracy of mileage measurement from centimeter level to millimeter level,and improves the positioning accuracy of survey points; field measurement instruments need not to be frequently moved up and down along the lines,thus improving the safety factor of operation and the efficiency of field survey; and a data processing program has been developed pertinently,which can dock the field data accurately and improve the efficiency of data processing.更多还原
