南京长江二桥八卦洲引线路基沉降观测和数据分析

The settlement observation and data analysis of the second nanjing yangtse river bridge ba-gua continent's roadbed

结合南京长江二桥八卦洲引线的路基沉降观测,对观测设施的布设、观测的技术要求等各项工作作了必要的介绍,采用统计方法对观测成果进行分析,以确定点位的稳定性,最后运用傅里叶变换方法分析测量数据时间序列在频率域上的变化特性,并在此基础上对可能存在的沉降规律作出分析,目的在于为工程管理部门提供决策依据,也用于指导类似工程的沉降观测工作。

In accordance with the settlement observation of the Second nanjing Yangtse River bridge Ba-gua continent's roadbed,the collocations of the observation point and technology terms of the ob-servation are gieven,the statistic analysis and the Fourier transforms are studied as well in processing the final data.It will be helpful to analyze the rules and the currents of the settlement provide decision-mak-ing reference to project-managing department,and prepare for the similar engineering.
