铁路既有线测量设计一体化技术的研发与实践
Development and Practice on Integrated Survey and Design Technology for Exiting Railway Lines
摘要
Abstract
The paper focuses on the failure of the conventional measurement method to reconstruct existing railway lines and provide theoretical center line coordinate for CPⅢ track-laying.With track-smoothness-oriented least square optimization method,with the control pile method fitting the theoretical straight line to construct existing theoretical centerline,with curve integral method based on basic design element threshold value,with the center line mileage of the survey point calculated by overlapping normal direction through model of circulation approach and with the data of designing interface obtained by interpolation of center line mileage,the existing railway line is reconstructed.A set of total station automatic collection data system for theoretical coordinates of railway center line and an integrated survey and design processing system are developed to fulfill the target to provide the theoretical centerline coordinate for existing line design.A complete set of theory methods and technology system are formed based on field measurements for office automatic design,which is verified by engineering practice and widely used.关键词
