京沪高速铁路CPⅢ监督测量解决方案

Solution of the CPⅢ Supervision and Surveying of Beijing-Shanghai High-speed Railway

对高速铁路及客运专线精密控制施工测量工作进行有效监督提出新的思路。详细介绍CPⅢ平面、高程控制网监督测量的精度指标、技术要求及作业方法。指出,为确保CPⅢ平面控制网和高程控制网的精确可靠,提高高速铁路及客运专线几何线形平顺性极其重要。

This paper offers a new thought on how to realize the effective supervision on the construction surveying of precise control of high speed railway and passenger dedicated line, and introduces in detail the precision index, technical requirement and operation methods of monitoring surveying by use of the CPⅢ horizontal and vertical control networks. Meanwhile, it expounds how important it is to enhance the geometrical alignment smoothness of passenger dedicated lines so as to assure the precision and reliability of the CPⅢ horizontal and vertical control networks.
