Paper presented at the ISRM International Symposium, November 19–24, 2000
Paper Number: ISRM-IS-2000-266
... ABSTRACT: On 12 April 1998, the strongest earthquake in the last century with an epicentre in Slovenia shook low a populated area in the Alps (The upper Soca Territory) of NW Slovenia. The earthquake of a local magnitude of 5,6 (MwA=6,0) caused no loss of life, although a lot of damage was...

... equilibrium state, even a slight earthquake may trigger it to destabilize. An intensive earthquake may directly cause a whole slope to fail. Kangding City is located in the intersection of three famous active seismic belts and thus with frequent earthquake activity. Many earthquakes occurred there in the past...

... Evaluation Earthquake (SEE) and Functional Evaluation Earthquake (FEE) are defined. The SEE event has only a small probability of occurring during the useful life of the bridge. The FEE is intended to represent an event that has a reasonable probability of not being exceeded during the life of the bridge...

.... The mechanism for the water film generation is clarified. Thus the significant effect of water film on land and submarine slides due to seismic liquefaction is demonstrated. INTRODUCTION In past earthquakes, landslides in alluvial sand deposits or lateral flow took place in coastal or river-side...

... ABSTRACT: Earthquake induced flow failures of saturated or partially saturated sloping ground have taken place in man-made earth structures during the past earthquakes. Conditions leading to such flow failures in infinite slopes with seepage water resting on stiff slopes were investigated by a...

... ABSTRACT: The aim of this study is to reveal the mechanism of damage to gravity type quay walls during an earthquake. The dynamic behavior of the quay wall was observed in model shaking table tests on various types of model caissons, with liquefaction of backfill. The transient feature of the...
