| Abstract: | The consultative anti-seismic design of Rongdong Bridge in Jieyang City,Guangdong Province is described. The seismic intensity regionalization and the classification of the site soil in the former design is reconsidered. Based on the structural characteristics of the bridge and the possible response of the bridge under seismic force,the foundation design is optimized. The anti-seismic level in the former design is checked according to the current communications specifications and the seismic response spectra. The anti-seismic level of the bridge is determined reasonably,and the construction cost of the bridge reduced. |
