【摘要】 本文依据国内外几次大地震中由于竖向地震力造成的地面震动、岩土体破坏、工程构筑物震害的实例和部分实测资料。简要地讨论了强震极震区内的竖向地震力现象和特点,认为竖向地震力是客观存在的,量级很大,是导致严重震害的重要原因。在进行重大工程选址、设计时应充分认识和重视竖向地震力的影响。以尽量消除和减少由于竖向地震力对重大工程带来的安全隐患问题。更多还原

【Abstract】 According to some earthquake damage examples of ground motion,rock(soil)failure and engineering structure damage due to vertical seismic force and some typical measurement data from several strong earthquake happened both home and aboard,the authors briefly discussed some phenomena and characteristics of vertical seismic force at meizoseismal area,and be convinced of its objective existence during strong earthquake.The vertical seismic force is very notable in magnitude and important factor causing serious earthquake damage.Therefore,it should be paid much more attention to and studied to diminish or reduce its hidden safety trouble to important engineering project as more as possible when choosing the site of and designing the important engineering project.更多还原
