non-expansion-joint long-connection viaduct and construction method thereof
The invention relates to a non-expansion-joint long-connection viaduct and a construction method thereof.The non-expansion-joint long-connection viaduct comprises a bridge deck structure and a plurality of bridge piers, the bridge deck structure comprises a main bridge and approach bridges arranged at the two ends of the main bridge, the multiple bridge piers are arranged in the length direction of the bridge deck structure, and expansion devices are arranged between the main bridge and the approach bridges for connection; the main bridge comprises a first part located in the middle and two second parts located at the two ends, a third part is arranged between the first part and the second parts for connection, a fixed support is arranged between the first part and the bridge piers, a friction pendulum seismic reduction and isolation support is arranged between the second parts and the bridge piers, and an acceleration locking support is arranged between the third part and the bridge piers. In order to meet the environmental requirements nearby hospitals, laboratories and chip production factories, only the telescopic devices are arranged at the two ends of the main bridge, the connecting length of the main bridge is large, the bumping vibration and noise of vehicles on the main bridge can be reduced, and the anti-seismic performance of the main bridge can be guaranteed through the fixed supports, the acceleration locking supports and the friction pendulum seismic reduction and isolation supports.
本发明涉及一种无伸缩缝长联高架桥及其施工方法，包括桥面结构以及若干个桥墩，桥面结构包括主桥以及设置在主桥两端的引桥，若干桥墩沿桥面结构的长度方向排列，主桥与引桥之间设有伸缩装置连接，主桥包括位于中部的第一部分、位于两端的两个第二部分，第一部分与第二部分之间设有第三部分连接，第一部分与桥墩之间设有固定支座，第二部分与桥墩之间设有摩擦摆减隔震支座，第三部分与桥墩之间设有加速度锁定支座。为满足医院、实验室以及芯片生产的工厂附近对环境的要求，其只在主桥的两端设置伸缩装置，主桥联长较长，可以减少车辆在主桥上的跳车振动与噪音，而固定支座、加速度锁定支座以及摩擦摆减隔震支座可以保证主桥的抗震性能。
