| 摘 要： | INTRODUCTION On Jan. 17, 1995, the Hyogoken-nanbu earth-quake in Kobe, Japan, caused great destructive and damage to underground structures, such as subway structures, mountain tunnels, multipurpose under-ground ducts and other underground structures, which had previously been considered to be resistant to earthquake effects (JSCE, 1996; ECRHAED, 1998). This earthquake revealed that a number of critical issues should be added in the seismic design and seismic strengthening of undergr…

| Abstract: | A series of scaled-model shaking table tests and its simulation analyses using dynamic finite element method were performed to clarify the dynamic behaviors and the seismic stability of embedded corrugated steel culverts due to strong earth-quakes like the 1995 Hyogoken-nanbu earthquake. The dynamic strains of the embedded culvert models and the seismic soil pressure acting on the models due to sinusoidal and random strong motions were investigated. This study verified that the cor-rugated culvert model was subjected to dynamic horizontal forces (lateral seismic soil pressure) from the surrounding ground, which caused the large bending strains on the structure; and that the structures do not exceed the allowable plastic deformation and do not collapse completely during strong earthquake like Hyogoken-nanbu earthquake. The results obtained are useful for design and construction of embedded long span corrugated steel culverts in seismic regions. |
