| Abstract: | After analyzing the allowable building errors of bridge piers in water areas,the essential accuracy of bridge construction control network is deduced.Then,the orders of bridge elevation control survey for different over-river distances,as well as the numbers of observation sets and groups in a half-set of over-river leveling are studied and designed.The research results could be used for reference by related specifications. |
