| 摘 要： | 针对统计回归计算中出现的水压因子难以入选和入选以后计算结果不合理的困难，本文应用偏最小二乘回归建立坝顶水平位移的统计模型。计算结果表明，相对于逐步回归和多元回归，基于偏最小二乘法的回归模型，取得较合理的结果。

| Abstract: | Considering that the water level factor is difficult to be selected and the calculated result is not reasonable. a statistical model of horizontal displacement for gravity dams is developed in this paper on the basis of partial least square regression. The result from the present the model is more reasonable that the result from stepwise regression and multiple regression. |
