针对河道水闸项目展开了地基处理方案及渗流稳定性分析。通过对水闸工程的工程概况、研究方法与分析、结果等进行深入研究和分析，揭示了水闸结构的渗漏特性和稳定性。通过SEEP/W程序和Geo-Studio2018的应用，采取了稳态分析等方法，对水闸基础的渗漏情况进行了详细分析。同时，采用统计分析和实地观测结果进行了验证，确保了模型的准确性和可靠性。结果显示，河道水闸在正常使用情况下不会受到渗漏的威胁，但在极端洪水事件中需要采取措施确保结构的安全。

This article presents a foundation treatment plan and seepage stability analysis for the river sluice project. Through in-depth research and analysis of the engineering overview, research methods and analysis, and results of the water gate project, the leakage characteristics and stability of the water gate structure have been revealed. Through the application of SEEP/W program and Geo Studio 2018, steady-state analysis and other methods were adopted to conduct a detailed analysis of the leakage situation of the sluice foundation. At the same time, statistical analysis and field observations were used to verify the accuracy and reliability of the model. The results show that river gates are not threatened by leakage under normal use, but measures need to be taken to ensure the safety of the structure in extreme flood events.
