长距离跨河水准测量是特大跨径桥梁建设中高程控制的一项重要内容。在分析长距离跨河水准测量误差影响因素的基础上,研制了灯体式跨河水准测量照准标志并用于泰州长江公路大桥二等跨河水准测量中,实践证明了灯体式标志适合于长距离的跨河水准测量,对保证测量精度和提高工作效率具有明显的作用。 Long-distance river crossing leveling measurement is an important part of elevation control in the construction of extra-long span bridges. Based on the analysis of the influencing factors of measurement error of long-range cross-river leveling, the light-body cross-river leveling sighting mark was developed and used in the second-level cross-river leveling measurement of Taizhou Yangtze River Highway Bridge. It has been proved that the light body type mark is suitable for long distance Of the river level measurement, to ensure measurement accuracy and improve work efficiency has a significant role.
