Static analysis of an arch gravity dam -A Case Study

Abstract

The Janneh dam is designed as an arch-gravity Roller Compacted Concrete dam (H=157 m), currently under construction in Lebanon. It was initially designed as a straight-gravity dam. However, due to seismic reasons, its layout has been curved. In the paper is performed numerical static analysis of dam Janneh, by spatial (3D) numerical models. Namely, the model consists of dam body and rock foundation. The analysis were executed by application of code SOFiSTiK. The behaviour of the contact zone dam-foundation was simulated by interface elements of type spring, by specifying input parameters for non-linear behaviour of the zone. The obtained results are compared with output results from executed analysis from different calculation codes.
