| Abstract: | 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. |
