| Abstract: | 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. |
