| 摘 要： | 蚌埠闸19口减压井建于20世纪60年代初,建成运行不久即淤堵严重。虽经数次清淤,但清后复淤,收效甚微,承压水位较工程运行初期逐年呈上升趋势。该文从井的外淤和内淤两个方面初步分析了减压井失效的原因,指出了原减压井设计上的缺陷。对今后减压井的设计和施工的改进可提供参考。

| Abstract: | 19# pressure-relief well of Pengpu Gate was built at the beginning of 1960s.It was seriously blocked up by silt at once after put into operation.Though the silt was cleaned for many times,the silting was again and it produces very little effect.The pressure-bearing water level presents the rising trend than at the beginning of engineering operation year by year.The article analyzes the losing efficacy reason of the pressure-relief well from two aspects of the external silting and the internal silting,and po... |
