武广客运专线接触网专业计算需要对线路参数进行测量,以往的中线交桩及高程点交桩模式已经不能满足测量精度及测量效率的要求。针对客运专线采用CPⅠ、CPⅡ、CPⅢ精测网的施工特点,为提高测量效率和保证测量精度,提出了结合客运专线精测网的支柱参数测量方法。 Wuhan-Guangzhou passenger line contact line professional calculation of the line parameters need to be measured, the previous mid-line cross-pile and elevation point cross-stake model can not meet the measurement accuracy and measurement efficiency requirements. In view of the construction characteristics of CP Ⅰ, CPⅡ and CP Ⅲ precision measurement network for passenger dedicated line, in order to improve the measurement efficiency and ensure the measurement accuracy, a prop method for measuring the pillar parameters is proposed.
