Abstract:

The finite elements with joint net is a powerful program which has the function of modeling actual joint net of rock mass slope, it not only permits in-situ statistic parameters of the joints to be input into the model directly, but also gives joints the right to yield according to a certain criterion and thus can better simulate the real rock mass structure of the toppling slope and failure pattern. The stability analysis method of the toppling slope and open questions are discussed; the function and input parameter of the finite elements with joint net are introduced; and its some advantages for stability analysis of toppling slope are explained. A case of toppling slopes from Cihaxia hydropower station at the upper reaches of the Yellow River is calculated using this method to analyze its stability and failure pattern. It is shown that the finite elements with joint net is an effective and matter-of-fact method for the stability analysis of toppling slopes

Key words: joint net, finite elements, toppling, slope, stability analysis
