南京长江二桥精密高程控制分析

The Analysis of Nanjing YanZi River 2nd Bridge Precise Vertical Control Survey

本文对南京长江二桥南汊河南、北吊索塔建造过程中,实施跨河水准精密高程控制方案做了论述,并对测量成果进行方差分析及F检验。结果表明:测量成果的精度好、可靠程度高,大大超出了预定的要求。为今后某些特殊要求的特种工程的精密高程控制提供了可借鉴的经验。

this paper discusses the executable project of precise river - cross leveling in the south and north sling poles construction of Nanjing YanZi River 2nd bridge, inspecting measurements by variance analysis and F - test. The results indicate that accuracy of measurements is high, dependability of measurements is high too, they surpass expected requirement, this offers recommendable experience in precise vertical control survey of some special type project with special request for the future.
