摘要:: 通过胶济客运专线既有工程测量网和精密工程控制测量网的对比研究,提出基于高精度测量网兼容低精度网的设计、施工分析处理方法,并在胶济客运专线施工图阶段平纵断面设计以及如何与现场施工相结合进行技术处理等方面进行了实际应用,减少设计返工与避免施工中的废弃工程。通过3年多的运营证明,胶济客运专线高精度测量网兼容低精度网的测设方法和成果、线路平纵断面设计处理方法,满足了建设、运营、维护的要求。

Abstract:: This paper compares existing engineering survey network and precise engineering survey network of Qingdao-Jinan passenger dedicated line, and puts forward a solution for design and construction that is compatible with both high precision and low precision engineering survey network, and it is practically used in plan and profile design of construction drawing and technical treatment combing with field construction of Qingdao-Jinan passenger dedicated line, which decreases unnecessary redesign and waste works in construction. More than three years of operation has proved that test methods and results of high precision and low precision engineering survey network and design of plan and profile meet the requirements of construction, operation and maintenance.
