| 摘 要： | 根据试验测定的不同循环次数下的海水侵蚀混凝土梁斜截面承载力，建立毫非线性的渐近回归分析模型，并采用遗传算法进行参数的优化计算，然后根据模型计算混凝土梁斜截面承载力，其结果与实测数据吻合较好，混凝土梁斜截面承载力计算值的平均相对精度在95％以上。因此，基于遗传算法的非线性回归模型可以用于海水侵蚀混凝土梁斜截面承载力的分析。最后，实现了混凝土梁斜截面承载力分析的智能化。

| Abstract: | According to the data of bearing capacity on oblique section of concrete beam in seawater in different circulation times, a non liner asymptotic regression analysis model is established in this paper. The parameters are optimized with genetic algorithms, then, the bearing capacity on oblique section of concrete beam is calculated with the model. The theoretical calculating and test results are identical, and the relatively average precision is over 95%. As a result, it can be used to analyze the bearing capacity on oblique section of concrete beam in seawater, realizing its intelligent analysis. |
