...J. Kuwano; Y. Miyata; J. Koseki ABSTRACT: The 2011 Tohoku earthquake off the Pacific coast of Japan (M_w = 9.0) contained a huge source region of approximately 450 km by 200 km and caused extensive damage to various structures. Damage caused by the tsunami was tremendous and many lives...

... of the damage to small earthfill dams that has taken place during earthquakes as well as heavy rainfall. The paper then describes a new technology using geosynthetic soil bags with extended tails stacked on the downstream slope to construct earthfill dams that are highly stable against earthquakes as well...

... soil-cement Seismic design Earthquake The geogrid-reinforced soil wall (GRSW) method has been widely used around the world, owing to its high seismic stability, economic advantages, and reasonable workability. In particular, many GRSWs have shown high seismic stability during past huge...

...M. Shinoda; K. Watanabe; K. Kojima; M. Tateyama; K. Horii ABSTRACT: The mid-Niigata prefecture earthquake in 2004 damaged a number of structures, including embankments, earth slopes and retaining walls. This paper describes a selected collapsed earth slope constructed in a valley eroded...

... the 1995 Hyogoken-Nambu earthquake, the effectiveness of the simplified approach for assessing seismic displacement of GRS-FHR walls was verified. These results were also compared with those calculated for some geosynthetic-reinforced walls with modular block facing that have been reported in a companion...

... accelerations. Both methods appear in the current design guidance document for conventional reinforced segmental retaining walls (Bathurst 1998). Post-earthquake observations have shown good performance for geosynthetic-reinforced systems including conventional segmental retaining wall systems (Koseki et...

...D. Choudhury; S. S. Nimbalkar; J. N. Mandal Determination of the external stability of reinforced soil walls under earthquake condition is an important topic of research for geotechnical engineers. In the present paper, a pseudo-dynamic method, which considers the effect of phase difference in both...

...). It is shown that the values of k h cr can be expressed using linear functions of parameters representing the geometry and the reinforcement configuration of the wall. It is also shown that horizontal seismic displacement of GR-MBWs subjected to three recent major earthquakes, namely the 1994...

...S. S. Nimbalkar; D. Choudhury; J. N. Mandal Determination of the internal stability of reinforced soil walls under earthquake conditions is an important part of seismic design. The horizontal method of slices is used for determining internal stability or for tieback analysis of the reinforced soil...

Measured footing and reinforcement loads are compared with values predicted using current...

... indicator of post-earthquake serviceability, this paper describes the development and validation of a practical model for estimation of the permanent displacement of reinforced slopes subjected to earthquake loading. The ability of the model to reasonably predict yield acceleration and time histories...
