Using Computer Modeling To Evaluate the Safety of Concrete Dams

摘要

Modern tools — including high-speed computers and finite element analysis software — are now readily available to evaluate the safety of concrete dams. These cost-effective tools let engineers perform analysis of structural behavior that closely models the actual performance of the dam. Concrete dams are valuable assets — they provide reservoirs for water supply, pressure head for power generation, and recreation areas. But many concrete dams, built as long as 100 years ago, are showing their age. In addition, understanding of material behavior, hydrology, hydraulic and seismic loads, and complex structural problems were in their infancy when these dams were built.
