摘要
为解决某大跨径独塔斜拉桥桥址区地震烈度较高,基础的纵横向弯矩及剪力较大,同时出现上拔力等问题,结合某独塔斜拉桥工程,从动力特性计算、抗震计算和主墩桩基础设计等方面介绍了大直径桩基在强震区独塔斜拉桥中的应用,以期为同类型桥梁工程参考。
In order to solve the problems of higher seismic intensity in the site of a long-span single-pylon cable-stayed bridge, larger vertical horizontal bending moment and shearing force of foundation, and also appearing of uplifting force, the article introduces the application of large-diameter pile foundation for the single-pylon cable-stayed bridge in the highly seismic region from the calculation of dynamic characteristics, the calculation of seismic resistance and the design of main pier pile foundation by an example of single-pylon cable-stayed bridge.
