摘要
以一座拟修建的预应力混凝土连续梁桥为对象 ,从梁桥体系、梁墩体系、梁墩基础体系 3个方面分析了高速列车过桥的车桥竖向动力特性。分析结果表明 :无论采用哪一种体系 ,车桥动力响应结果几乎相同。此外还分析了刚性基础墩身和弹性基础墩身的动力响应问题。
In this paper, the vertical dynamic response of a P.P.C. continuous bridge, which will be built in future is analyzed with girder system, girder-pier system and girder system including pier and foundation. The results show that no matter which structure system is adopted the dynamic response of the bridge is always the same. In addition, the dynamic response of a pier with rigid foundation or pier with elastic foundation is also analyzed.
