چکیده
|
In layered and blocky rock slopes, toppling failure is a common mode of instability that may occur in mining engineering. if this type of slope failure occurs as a consequence of another type of failure, it is referred to as the secondary toppling failure. “slide-headtoppling” is a type of secondary toppling failures, where the upper part of the slope is toppled as a consequence of a semi-circular sliding failure at the toe of the slope. in this research work, the slide-head-toppling failure is examined through a series of numerical modeling. phase 2, as a software written based on the finite element method, is used in this work. different types of slide-head-toppling failures including blocky, blockflexural, and flexural are simulated. a good agreement can be observed when the results of the numerical modeling are compared with those for the pre-existing physical modeling and analytical method.
