The Present Study Situation of Seismic Isolation by Sand Gravel Underlayer and Several Questions Concerned

摘要：

Expatiate the application of sand gravel underlayer for seismic isolation and Productions about these that have been studied. Offered disagreement about the calculation mode of sand cushion for some scholars. Suggested it should allow a certain extent sliding displacement take place of constructions building on sand cushion. Also suggested the content of define the vibration reduction ratio.

关键词： sand gravel underlayer seismic isolation calculation mode sliding displacement responses spectrum vibration reduction ratio
