摘　　要：桥巩水电站采用橡胶坝作为二期上游过水土石围堰的子围堰,利用橡胶坝可升坝挡水、坍坝行洪的特点,在不增加施工期临时淹没的情况下,提高了上游发电及通航水位,取得了较好的经济效益。Rubber dam was used as a sub cofferdam for the second phase upstream overflow earth-rock coffer- dam of Qiaogong hydropower station, which can retain water when aerated and discharge flood when deflated. The use of rubber dam raised the upstream water levels for navigation and power generation without increased flood damages in construction period, and achieved good economic benefits.
