FINITE SLIDING BEARING, SEISMICALLY ISOLATED FOUNDATION STRUCTURE, CONSTRUCTION METHOD OF FINITE SLIDING BEARING

摘要

PROBLEM TO BE SOLVED: To enable a finite sliding bearing to be easily constructed at a low cost by laying a thin sand layer.SOLUTION: The finite sliding bearing comprises: a foundation pit 2 which supports a load of a construction 10 and has impermeability; a sand layer 3 with a predetermined layer thickness laid on a bottom slab 21 of the foundation pit 2; and storage water 4 stored in a receiving section 2A of the foundation pit 2 with the construction 10 directly supported on the sand layer 3. The sand layer 3 is kept in a saturated state and used as a seismically isolated foundation structure of the construction 10.SELECTED DRAWING: Figure 1
