Abstract

Combined with seismic resistance of T shape rigid bridge with high piers in Dina 2 gas-field of China, comparative analysis on double thin-wall piers and hollow thin wall pillar is carried out. Focusing on seismic performance of their dynamic properties and structure under the condition of one-way incentive and three-dimensional space incentive, we conclude that the seismic performance of double thin-wall piers is superior to hollow thin wall pillar, on the basis of the fact that double thin-wall piers contains more than hollow thin wall pillar low-frequency vibration frequency in sectional characteristic and pier under the condition of high basic agreement, which is easily causing to frequency dispersion.
