| dcterms.abstract | A mode of slope failure initiating a great number of rock falls is toppling, which occurs in rock mass under gravity alone and the joints inclined into the hill, such as, in columnar-jointed volcanics and regularly jointed granitics in Hong Kong. Therefore, we can not ignore them in the slope stability. The effect of joints including crossing and vertical in toppling slopes has been discussed in this report and the project models are the block flexure toppling, a kind of toppling failure (defined by Goodman, 1976). Furthermore, the improved Base Friction Apparatus and digital camera can show the failure procedure clear and get further knowledge of toppling mechanism. Moreover, the kinematics model tests are performed in different geometry of joint distribution. It is a note that the joint spacing, interaction between two joint sets, the key block on the slope toe and the relative density of joint have great influence to the slope stability. Finally, some testing results can be used in the slope engineering. | en_US |
