This paper introduces the using of the technique of RTK to topographic survey for Hangzhou Bay Major Bridge, it also provides comparison and analysis for the result gotten by RTK, the error gets from one point would not deliver to the other, and the results coincide with that get from TS(total\|station)etc. So it can be used to replace the second\|class of third\|class traversing and out\|order leveling; When the distance between the flowing station and the reference station is not beyond 10 km the RTK shows a more convenient and more quick character in the under\|water terrain surveying, but when it is beyond 10 km the accuracy could not be guaranteed. In the process of Hangzhou Bay Major Bridge building the RTK must be used in location and altimetric surveying because it can boost the working efficiency and the quality of the achievements.

介绍了RTK技术在杭州湾跨海大桥桥位地形测绘中的应用,并对其定位结果进行了精度比较与分析,结果表明:RTK定位测量的点位精度可达厘米级,各点位之间不存在误差积累,与全站仪等测量手段取得的结果符合得较好,可以用来代替二三级导线控制测量和等外水准等测量方法;流动站与基准站的距离在10km范围以内时,应用RTK技术对近岸水下地形进行测量具有方便、快捷、精度高等特点,但当此距离超过10km时,其精度则难以保证。杭州湾跨海大桥施工时应用RTK技术进行定位、高程测量,可提高工作效率和成果的质量。

The underwater topography of the Hangzhou bay is very complicated and its tide is so strong, that arranging the tide stations reasonably, calculating the tide lever by using triangle zone method and surveying in proper time can get more precise data. Usually, start to survey between 3 hours before high tide and 3 hours after high tide, can succeed in averting the forth brank while linking up survey of shallow tidesand. It is an available way that examine line must be layed on surveying water depth in order to...

The underwater topography of the Hangzhou bay is very complicated and its tide is so strong, that arranging the tide stations reasonably, calculating the tide lever by using triangle zone method and surveying in proper time can get more precise data. Usually, start to survey between 3 hours before high tide and 3 hours after high tide, can succeed in averting the forth brank while linking up survey of shallow tidesand. It is an available way that examine line must be layed on surveying water depth in order to examine water depth product and tide rectification. So the pricsion of landforms survey can be improved.

杭州湾跨海大桥桥位地形测绘中,采用三角分带解析法进行潮位改正计算,结果表明:合理布设潮位站、合理安排测量时间,可以提高地形测量精度,正确地进行潮位计算。一般应在高平潮前后3h时间内施测,可保证浅滩不出现测量空白区。地形测绘过程中还应布设不少于主测线数量的5%的检查线,以检查其测量精度。在所测的河口湾两岸潮位明显不等时,采用三角分带解析法进行潮位改正计算,其结果合理、正确,可达到规范的要求。

During the researches of the Hangzhou Bay Major Bridge, based on the sufficiency research and evaluation, we put forward the navigation headroom yardstick of south navigation channel and the navigation channel central\|line, which provide an important basis for the design of the Hangzhou Bay Major Bridge.

在杭州湾交通通道预可行性研究阶段的《通航标准论证报告》及杭州湾交通通道有关专题研究成果的基础上,依据浙江省交通厅文件的精神,结合杭州湾的水文、河势、港口、航道等基本状况、条件以及通航船舶现状与未来对通航发展的要求等,确定了杭州湾跨海大桥南航道的通航净空尺度和桥位航道中心线及通航孔的位置。在杭州湾南航道中心线设了3个通航孔,其中1个为主通航孔,2个为副通航孔。主通航孔可通行总长为97m,宽为14m的3000t级杂货船,净空高度不于31m,净空宽度不小于125m,单向通航;副通航孔可通行总长小于33m,宽为7.2m的小型船舶,净空高度不小于20m,净空宽度不小于50m,单向通航。最高通航水位为5.19m。
