葛洲坝水利枢纽大江上下游横向围堰自1981年元旦截流填筑,1982年2月基坑抽水完毕投入使用直至1986年拆除,已安全运行了四年.圆满完成了围堰的任务.原先人们所担心的渗流问题亦都得到较好的控制.那么,葛洲坝水利枢纽大江围堰的成功之处到底在那里?它有那些经验可以借鉴?本文皆在从渗流试验及渗流观测研究两方面作一系统回顾,对大江下游围堰最突出的渗流问题作一初步总结.供有关方面参考.
The Gezhouba Water Control Project The upper and lower reaches of the river bank have been cofferdams closed since January 1981. After excavation of the foundation pit was completed and put into operation in February 1982, it has been safely operated for four years and the cofferdam has been successfully completed. The problem of seepage that is worried about is also well controlled.However, where is the success of the large cofferdam of Gezhouba Hydropower Station? What experiences can it draw lessons from? In this paper, we make a systematic study from the aspects of seepage test and seepage observation In retrospect, a preliminary summary of the most prominent seepage problem of the cofferdam at the lower reaches of the river is provided for reference by relevant parties.
