Granite Creek Dam, the Progressive Stability Analysis

摘要

URS Corporation recently preformed a comprehensive structural stability analysis of Granite Creek Dam, a concrete-arch dam located in Prescott, Arizona. The analysis used both linear and non-linear finite element models (FEMs) to simulate the structural behavior of the dam and evaluated the behavior due to usual, unusual, and extreme loads. This paper discusses the basics to the analysis, parameter studies, and presents a method to evaluate the stability of the dam at the dam/foundation interface, called progressive stability analysis (PSA).
