:1998年8月7日,九江市长江干堤4～5号闸口间发生溃口,经2万多军民奋战5个昼夜堵口成功,创造了我国堤防溃口堵口史上的奇迹。九江溃口形成7m冲坑,溃口下段地层中含有淤泥质土,为了确保复堤后的堤防工程安全,必须对堤基进行处理。全面阐述了溃口复堤段地形、地质条件,堤防现状,溃口复堤方案,堤线布置,堤型选择,堤基处理,安全监测等设计原则,分析计算成果。并根据1999年汛期(最高水位22.43m,居历史记录第二)监测资料,对溃口复堤防渗工程的防渗效果作了定性和定量分析
: August 7, 1998, Jiujiang City, the Yangtze River dry embankment 4 to 5 between the mouth of the breach, after more than 20,000 troops and civilians fought five day and night clogging success, creating a miracle in the history of China’s embankment breach. 7m crater was formed at the mouth of Jiujiang River and muddy soil was formed in the lower part of the breach. In order to ensure the safety of dike after dike embankment, the dike foundation must be treated. The design principles of topography, geological conditions, embankment status, dikes embankment scheme, embankment layout, embankment type selection, embankment type selection, embankment treatment and safety monitoring are all expatiated and analyzed and calculated. Based on the monitoring data of the flood season in 1999 (the highest water level of 22.43m and the second historical record), the seepage-proofing effect of the seepage-proof embankment seepage control project was qualitatively and quantitatively analyzed
