摘　　要：系统地分析和总结桥梁工程跨河水准测量的基本理论、方法和技术要点,对各种跨河水准测量方法的适用条件及其优缺点进行分析比较。最后,以某特大型桥梁工程的三角高程跨河水准测量为例进行了验证。Based on rich project practice, the elementary theory, methods and technical points of the river-cross leveling of bridge project were systematically analyzed and summarized. Comparisons among various methods of cross-river leveling in applicability, advantages and disadvantages were taken. Finally, with an extra large bridge project as the example, the method and techniques of cross-river leveling were validated.
