Abstract: This paper discusses investigations of potential block hazards in ten existing American concrete arch and buttress dams. Block theory was used to identify and describe all removable blocks, based on the study of construction ...

Abstract: The mechanical response of rock slopes and excavations depends largely on the geometry of discontinuities and associated rock blocks. Commonly used rigid block models for determining stability, such as the sliding wedge ...

Abstract: Scott Dam is owned and operated by Pacific Gas & Electric Co. (PG&E) as part of the Potter Valley Project. Although it is an unimpressive concrete gravity dam [233 m (765 ft) long with maximum water surface 33.4 m (110 ft) ...

Abstract: The behavioral modes to which a rock slope is susceptible are many and complex. This article discusses a long but not exhaustive list of common failure styles, highlighting observable characteristics that distinguish one ...

Abstract: A specific analytical solution for flow through a horizontal crack of finite length drained by a series of vertical drains is presented. The solution is used to derive diagrams of uplift pressure on the base of a dam and ...
