Abstract

Landslides are the mass of rock, debris and or earth that moves down a slope by gravity. Study on landslide dynamics, including the dynamic of loading and excess pore-pressure generation and dissipation, is necessary to understand the initiation and motion of rapid landslides. This paper presents the development of ring shear apparatus that can facilitate the simulation of landslides, particularly for the formation of shear zone and followed by long and rapid shear displacement. A series of different types of ring shear apparatus (i.e. DPRI-3, 4, 5, 6 and 7) were developed by Prof. K. Sassa and his colleagues at the Disaster Prevention Research Institute (DPRI) of Kyoto University. The application of this apparatus to study the earthquake-induced landslides and landslide-triggered debris flow in Japan are explained in this paper. In addition, the tests using a transparent shear box of the DPRI-7 for visual observation of the shear zone during rapid shearing are also described.

Acknowledgements

We acknowledge the support of Scientific-Grant-in-Aid (No.03556021) of the Ministry of Education, Science, Culture and Sport of Japan in 1992 for the development of DPRI-3 (Sassa 1994), as well as DPRI-5 and DPRI-6 for the mitigation purpose of the Hyogo-Ken Nanbu earthquake. The help from Dr. Zieaoddin Shoaei and Dr. Fawu Wang for the system improvement and testing procedures are highly appreciated. The DPRI-7 was developed with support from APERIF Project, funded by Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT). The project was approved by the International Consortium on Landslides (ICL) as the IPL M-101 APERITIF Project. Many thanks go to all colleagues of the Research Centre on Landslides of the DPRI, Kyoto University for their cooperation.
