现代有轨电车工程测量技术的研究与应用

Research and Application of Modern Tram Engineering Survey Technology

在有轨电车工程建设过程中,轨道施工的质量直接关系到运营后列车的安全、舒适,是有轨电车施工的核心,具有质量控制严格,精度要求高的特点。电车的安全及平稳运行在一定程度上取决于钢轨的线形平顺及高稳定、高精度的轨下结构施工,而钢轨的精调整理以及精密的线下结构施工均是建立在精密工程测量控制基础之上的。工程测量工作贯穿着有轨电车勘察设计、工程施工及运营维护的全过程,是各阶段(设计、施工、运营维护)管理工作的标准和基础之一。本文针对我国现阶段有轨电车建设现状,并结合武汉有轨电车施工实际案例,对有轨电车施工和运营过程中精密工程测量的主要工作内容和技术方法进行了研究和应用,对完善有轨电车精密工程测量控制体系,形成一整套成熟的应用流程具有一定的参考和借鉴意义。

During the construction of the urban tramway project,the quality of the track construction is directly related to the safety and comfort of the train after operation.It is the core of tramway construction,with strict quality control and high precision requirements.The safe and smooth operation of the tramway depends to a certain extent on the smooth linearity of the rail and the construction of a high-stability,high-precision under-rail structure,and the fine adjustment of the rail and the precise construction of the offline structure are based on precise measurement control.Precision measurement control runs through the whole process of survey,design,construction and operation and maintenance of tramway,and is one of the standards and foundations for the management of each stage(design,construction,operation and maintenance).Aimed at the current situation of the construction of trams in China,and combined with the actual case of Wuhan tram construction,this paper analyzes and summarizes the precision engineering measurement and control technology during the construction and operation of trams,which has certain reference significance for perfecting the current precise measurement and control system of tramway and forming a complete set of mature application processes.
