Abstract: Based on the basic idea of Sara method, A sliding block computational model for the anchored slope is established in this paper after taking into consideration the action of earthquake and influence of underground water as well as the supporting effect of rock-bolts . This model has been applied to stability analysis for the high slope project of a hydropower station and conclusions of significance to engineering design has been got.

Abstract: There are large number of intermittently jointed cracks in rockmass, which exist in rockmass as a kind of initial damage. It is their damage, propagation and propagating interaction that result in a variety of failure forms of rockmass. This paper conducts an in depth research on the influence of cracks propagation interaction upon fracture strength of jointed rockmass. A kind of fracture strength model for jointed rockmass is developed under three-dimensional stress conditions. With the utilization of this model in a large-scale highway slope project, the design and construction are effectively performed and remarkable economic benefit has been achieved.
