三峡库区消落区库岸治理施工特点及导流度汛方案

摘要

为了总结三峡工程正常蓄水运行后，三峡库区消落区库岸治理工程施工特点及导流度汛的规律，在分析三峡水利枢纽调度运行方案、三峡库区消落区概况、三峡库区气象特点和洪水特点的基础上，结合近几年三峡库区消落区库岸治理工程实践，总结出三峡库区消落区库岸治理工程反季节施工、受暴雨和洪水影响大、可施工时间短、施工强度高的特点，提出利用库区低水位时段施工，不设围堰导流，库水位上涨时及时撤离的度汛方案，为三峡库区消落区库岸治理提供参考。%The operation scheme of the Three Gorges Junction , general conditions of the water-level-fluctuating zone of the Three Gorges Reservoir , and the specific meteorological and flood characteristics of the reservoir area are analyzed firstly.Then, based on the engineering practice of the reservoir bank treatment work in the water -level-fluctuating zone in recent years , the construction characteristics of the work are summarized , such as the off-season construction , strong influences of the heavy rain and flood , relatively short time that allows construction , and high construction intensity . Considering these characteristics , an effective diversion scheme is proposed , in which the construction should be carried out in the low water level season without cofferdams and stopped and evacuated timely when the water level rises .It could be a useful reference for the reservoir bank treatment work in the water-level-fluctuating zone of the Three Gorges Reservoir.
