Stability Analysis of Dam Foundation with Karst Cave

Abstract:

Article Preview

Stability of dam foundation with Karst caves is analyzed in the presented work.Conceptual model is established according to load analysis such as dam gravity and water press. The curve of point safety coefficient on the structure plane is draw out by using stress checking method.With the comparison of curves under different work conditions, it shows that the most dangerous position of Karst cave is at the dam toe area,with the increasing of dip angle of the structure plane,the safety coefficient declines.Then the possible damage zones,mechanism and failure mode of the dam foundation with Karst caves are analyzed. The result can be used in evaluating the stability of dam foundation with Karst cave.
