Application of DDA to Evaluate the Mechanism of Rock Slope Instability

摘要

In order to analyze failure of rock slopes, numerical method will be extremely useful. However, it will be difficult to simulate collapse, considering difficulties of obtaining rock parameters, such as geological conditions into numerical calculation. In this paper, in order to clarify the rock mass failure process provided in rock mass monitoring, we applied a failure judgment standard for the existing-discontinuities and the new discontinuities. From the application example to rock mass failure monitoring of Amatoribashi-Nishi site, it was clear that failure behavior such as a failure mode could be simulated well by DDA.
