| Summary: | 碩士 === 國立臺灣大學 === 土木工程學研究所 === 100 === This study presented the shaking table tests results of a scoured bridge-pile system carried out in National Center for Research on Earthquake Engineering (NCREE) through a bilateral laminated sand box. The experimental program was characterized by the scouring depth regarding to the diameter D of the pile. The time history results in each case were compared with those obtained from simplified analytical models with linear soil springs. New methods used in the analytical models include the modified locations of soil springs, the calculation of shear wave velocity of soil, and so on. The simulation results of acceleration and displacement are well satisfied with the test data earthquake excitations under 200 gals, particularly at the mass center of the single-degree-of freedom bridge system. It is expected to effectively predict the dynamic response of the scoured bridge with soil-structure-interaction issue.
