INVESTIGATION ON FAILURE OF GRANITIC RESIDUAL SLOPE BY USING CENTRIFUGAL MODEL TEST

This paper presents centrifugal analogous model of the sub-soil slope and associated matching scales of some parameters. The test results from the centrifugal model experiments show that the granite residual soil slope will probably fail in two modes: plane failure and arc sliding. The effects of water content are also analyzed. The relationship of gradient and corresponding critical slope height of the slope without significant constructional surface fits Masilofo equation.
