Cause analysis and treatments of face cracks for concrete face rockfill dam of Elesai Downstream Hydropower Station in Cambodia

Abstract

Abstract:

In the first phase construction process of concrete face rockfill dam of Elesai Downstream Hydropower Station in Cambodia, intensive cracks appeared on the face after the concrete pouring. According to the situation analysis, the main cause of cracks on face is the differential settlement of dam and the reverse water pressure inside the dam intensified the development of cracks and deformations. This paper introduced the treatments of the cracks and its effect, and summarized the experience and lessons in the construction process of concrete face.

Key words:
