测距三角高程法在平潭海峡大桥跨海水准测量中的应用

摘要

The thesis mainly introduces that without a more advanced approach to measure the sea or river with the width of more than 3km,trigonometric leveling method is used to accurately measure the river-crossing leveling of both shores while building Pingtan Strait Bridge,which successfully transmits the height between both coasts,and meets the standards of measurement and the requirements of bridge designing so that it can provide a precedent and some experi-ence for the height control of long-distance bridges.%目前对于跨度大于3 km的跨海（河）水准测量尚无其他先进的测量方法前提下，本文介绍利用测距三角高程法对平潭海峡大桥建设点的两岸实施跨海水准测量，成功地对两岸的高程进行了传递，且满足了测量规范和桥梁设计要求，为今后长距离的桥梁的高程控制提供了经验。
