Particle Flow Simulation

By biaxial test of soil particle flow simulation program, the corresponding relationship between macro and micro parameters were obtained firstly. And then the slope model was established accord with these parameters. With this model, the slope stability under load were analyzed numerically, the influences of applied loading area on slope stability and damages were compared. Results shown that a slip surface came when slope was broken under a few loaded area, which is called the main slip lines. With the movement of the sliding, other landslide cracks began to appear; when subjected to a large load area, the slope undermining the main slip line was not obvious, but there were multiple landslide fissures, along with the movement of soil, the speed of slope failure increased, and severely damaged instantly.

The Shuibuya Dam is the highest concrete faced rockfill dam (the height is 233m) in the world. The dam site is located in Enshi Autonomous Prefecture, Hubei province, china. The reservoir level is a maximum of 400m. When the dam was partially completed, water impoundment was started. On May 10, 2007, when the reservoir level achieved at 289m, a landslide located on the bank of Modao-he River moved rapidly, a tributary of the Qingjiang River. 14 houses collapsed and moved into the river, but nobody was killed due to timely geological prediction. For the purposes of landslide disaster mitigation in the reservoir areas and identification of landslide movement and deformation caused by the change of reservoir level, some researches were conducted, such as geological exploration, some soil tests and numerical simulation and monitoring system. In this paper, the causes of landslides and slope failure mechanism and the stability of slope were simulated by using DDA method and FLAC3D for the different reservoir’s level.

Sediment Disaster

At the end of July 2004, Typhoon 0410 struck the Naka River basin in Tokushima Prefecture, triggering numerous slope failures, killing two residents, and largely or totally destroying many houses. We examine this sediment-related disaster and the phenomenon of landslide dam formation in which slope failure triggered by torrential rain blocks the river course. In Atsue, Kisawa Village, the landslide slope failure was 1,000 m long and 100 m wide. Such large slope failures may form landslide dams, greatly influencing the effluence of water and sediment in mountain basins. Using a numerical simulation model, we reproduced the process in which failed sediment forms a landslide dam and applied it to the case occurring as a result of Typhoon 0410.
