A slope stability problem in Hong Kong - rocscience.com

A slope stability problem in Hong Kong Introduction In the early 1970s a series of landslides occurred in Hong Kong as a result of exceptionally heavy rains. These slides caused some loss of life and a significant amount of property damage. Consequently, an extensive review was carried out on the stability of soil and rock slopes in the Territory.

Rock Slope - an overview | ScienceDirect Topics

Stability analysis of a rock slope requires assessment of shear strength parameters, that is, cohesion (c) and angle of internal friction of the rock mass. Dilatancy in a rock mass is unconstrained near slopes as normal stress on joints is small due to weight of the wedge.
