Abstract:

The finite element analyses of a concrete faced rockfill dam (CFRD) with and without extrusion-sidewall are carried out using a simplified equivalent numerical model of extrusion-sidewall. Furthermore, a special condition of a CFRD with extrusion-sidewall only on the upper half is considered to investigate the effect of the form of extrusion-sidewall. The analysis is focused on the slab face stress and deformation. Calcalation results show that the distribution of deformation of dam and slab is insignificantly affected by the extrusion- sidewall, and the stress of slab and the settlement of the peripheral joint along the face edge are changed because of the adoption of extrusion-sidewall. The extrusion-sidewall has insignificant effect on the safety of the dam.

Key words: CFRD, extrusion-sidewall, interface, safety of dam, finite element analysis
