Some results are indicated that horizontal and vertical seismicforce must simultaneously be considered in the seismic study and design of the prestressed-arch structures.
结果表明，在预应力拱架结构的抗震研究中，需同时考虑水平和竖向地震作用。

When the earthquake happens, seismichorizontalforce will transfer into pier through energy dissipation device.
地震发生后，梁体地震水平力将通过减震装置传至桥墩。

The numerical results reveal that a great horizontalforce acting on the aqueduct body may occurred during strong earthquake. This action must be considered in seismic resistance design.
