Abstract

Stability of embankment dam with diaphragm cutoff wall constructed on riverbed sediment depends on structural behavior of local part around top of the wall. A numerical method to evaluate static and dynamic behavior of the part including earth pressure concentration is proposed and the validity is confirmed by comparison of numerical results of full construction process with observed ones in a prototype dam. Besides, in-situ vibration tests are performed on testing diaphragm wall constructed in dam site for banking test to reveal dynamic behavior of the wall. Furthermore, earthquake response analysis of whole structure is carried out to clarify behavior of a system of dam diaphragm wall and riverbed sediment during earthquake.

Soil-Diaphragm Wall Interaction in Floating Dam
