龙背湾水电站工程施工导流度汛方案变更优化设计

摘要

龙背湾水电站工程原施工导流度汛方案大坝临时度汛断面的施工强度高，施工时段还受围堰防渗施工和坝基处理等因素影响，度汛工期偏紧。根据工程地质条件特点，考虑到围堰仅使用一个汛期，适当调整导流度汛方案，可优化施工组织设计，节省工程投资。%Original construction diversion flood season plan of Longbei Bay hydropower station has high construction strength in dam temporary flood season cross section. The construction duration is also affected by cofferdam leakage control construction,dam foundation treatment and other factors. The construction schedule in the flood season is tight. Since the cofferdam is used only for one flood season,diversion flood season plan is suitably adjusted for optimizing construction organization design and saving project investment according to geological condition features of the project.
