葛洲坝基础排水孔过滤体运行状况研究

Analysis on Working Status of Drainage Hole Filters inside Gezhouba Project Foundation

葛洲坝基础排水孔过滤体运行25年来进行了多次检测以监控其运行状况。在历次工作基础上,对过滤体工作状态进行了分析,评价了排水孔的有效性。研究结果表明:组装式过滤体在运行25年后仍能满足工程要求并可以继续使用。

The drainage hole filters inside Gezhouba Project foundation have been operated for over 25 years. Their working statuses are analysed based on the monitored results. The filters are in good working order. The assembly filters can still satisfy the engineering demands after working for 25 years.
