| 摘 要： | 南京大胜关长江大桥六跨连续钢桁拱梁施工测量采取钢梁施工前对主桥控制网进行复测和加密,对六跨连续钢桁拱梁范围内墩、台进行贯通测量;施工监测阶段建立钢梁监测局部控制网;桥面系施工时建立桥面控制导线的方法,满足钢梁施工各阶段控制测量的需要。既保证主桥钢梁中心线与南京大胜关长江大桥桥梁中心线、京沪高速铁路线路中心线协调一致,又保证钢梁各个节间监测数据的测量精度,满足钢梁安装线形及合龙口线形调整的需要。

| Abstract: | The construction control survey of the six-span continuous steel truss arch girder of Nanjing Dashengguan Changjiang River Bridge proceeded in a way of re-checking and securing the control network for the main bridge first before the construction of the girder,carrying out the connecting survey for all the piers and abutments within the range of the girder,establishing the local control network for the girder at the construction monitoring and control stage and the deck control alignments before the floor s... |
