Some results are indicated that horizontal and vertical seismic force 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, seismic horizontal force 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 horizontal force acting on the aqueduct body may occurred during strong earthquake. This action must be considered in seismic resistance design.
计算表明：强震时，流体对槽身可能会产生很大的横向水平力，建议在抗震设计时考虑这一作用因素。
