摘要
探讨了桥梁结构跨越断裂带的六个关键问题:近断层地震动的基本特征,近断层地震动的模拟与预测,近断层地震作用下桥梁结构抗震性能分析,影响桥梁结构动力响应的近断层地震动参数,高性能桥梁减、隔振支座的研发,近断层区桥梁抗震设计理论及规范。
The article discussed 6 primary issues of bridge structures across fracture zones, which are basic features of earthquake motion adjacent to fracture zones, simulation and prediction of earthquake motion adjacent to fracture zones, analysis of earthquake-resistance performance of bridge structures under the action of earthquake motion adjacent to fracttLre zones, effect factors of bridge structures dynamic response of earthquake motion adjacent to fracture zones, research and development of high performance bearings for damping and isolating vibration, theories and codes for seismic design of bridge structures adjacent to fracture zones. Then, prospection was taken for future study.
