Evaluation of Rock Slope Stability Considering Size Effect and Time Dependency and its Application to Landslides around the Three Gorges Reservoir

摘要: Size effect and time dependency are observed in most rock or bedrock. A lot of researches have been performed on both them up to now. However, many points left unsettled although they considered be important especially for long-term stability a large structure.In this study, slope around the Three Gorges reservoir was discussed considering size dependency. There still not so related stability, it is difficult presume relationships between theoretically experimentally. So, study estimated by data analysis apparent friction nominal dimension landslides occurred past.Time concerning collapse landslide well known. If remarkable, just relatively low stress can lead gradual deformation then final failure. For evaluating of, example, 100 years, necessary understand rock. reason, collected situ tested laboratory obtain recently developed testing method with small specimens.Overdesign factor required calculated based The overdesign factor.
