摘　　要：在长江深水航道一期工程白茆沙整治工程中,部分堤身采用了半圆体混合堤结构。根据工程实际情况,对堤身结构选型进行了比较分析,对半圆体结构受力和构造进行分析研究。工程实践运用表明,该结构稳定性优,实现了整治建筑物的功能要求,应用效果良好。The semi-circular structures were used as part of the dam body of Baimaosha waterway regulation engineering of the Yangtze River deepwater channel phase I project.According to the actual working conditions, this paper analyzed and compared different options of dike structure types, and recommended the semi-circular structures as a selection scheme.Based on this, the force and construction of semi-circular structures were further analyzed and the results were shown and verified by practice. The practical application showed that the structures owned the feature of excellent stability, and well achieved the functional requirements of the engineering.
