摘要： 长江一级阶地地层具有典型的二元结构，临江地段地下水与地表水互补关系密切，地下建（构）筑物的抗浮设计水位受积水深度、基础埋深、基底下土层及长江地表水历史水位等多种因素影响；三峡大坝修建后长江武汉段今后可能达到的最高水位直接影响到抗浮设计水位取值。对不同基础埋深情况下的抗浮设计水位及当前长江武汉段最高水位取值进行了综合分析及建议，对长江沿岸类似地区抗浮设计有一定参考意义。

Abstract: The subsurface condition of the first terrace of Yangtze River in Wuhan has a distinct two-layer structure. The surface water is well connected with the groundwater at areas close to the river. As a result, the buoyancy design of the structures in these areas are associated with the groundwater level, foundation embedment depth, subsurface conditions below the foundation as well as the historical groundwater levels in the area. The future maximum flood water level after the Three Gorges Project construction is critical to the buoyancy design. This paper presents the results of the buoyancy design under various groundwater levels and different foundation embedment depths.
