Reason analysis and restoring treatments of face destruction for a certain concrete face rockfill dam

Abstract

Abstract:

In the first phase construction process of a certain hydropower station, structural damage and cracks appeared on the face. In this paper, the face destruction was checked and the damage reasons were analyzed firstly. After that, some face restoring treatments were proposed according to the stress features of concrete face and local actual conditions. After the restoring, the deformation of concrete face became stable and the leakage was controlled within the permissible range. At last, this paper summarized the problems that need attention in face restoring process and provided a reference for similar construction project of concrete face rockfill dam.

Key words:

">">concrete face rockfill dam；disengaging；crack；restore
