摘　　要：某隧道穿越段江堤发生了渗流,通过对地质条件、探测结果等方面的研究,进行渗流产生原因的分析:该段江堤情况复杂,历经多次工程建设,江堤堤身及下部堤基可能受到扰动,堤防土质变松散,形成了渗水通道。结合江堤实际情况,提出了消险加固方案,并进行了多项稳定复核。本案例总结的经验和教训,可为其它类似江堤提供经验和参考。The seepage happened in the embankment of a tunnel crossing section. Through the study ofgeological conditions and detection results, the causes of seepage were analyzed. The embankment conditionsin this section were complicated, and the embankment body and the lower embankment foundation might bedisturbed after many construction projects. The soil quality of the embankment became loose and the seepagechannel was formed. Combined with the actual situation of the river embankment, a scheme for eliminatingdanger and strengthening was put forward, and a number of stability checks were carried out. The experienceand lessons learned from this case could provide experience and reference for other similar river embankments.
