| 摘 要： | 根据汶川地震中绵阳市受损土石坝的实测数据,以大坝所在位置的地震烈度和地震发生前大坝的性态等因素作为预测因子,构造出土石坝震损裂缝预测的投影指标,采用可变阶的正交Hermite多项式拟合岭函数,并用单纯形算法优化投影指标函数,进而构建基于投影寻踪回归分析的震损裂缝预测模型,并将其用于该地区96座震损土石坝进行裂缝预测.将...

| Abstract: | According to the survey data of damaged earth-rock dam in Mianyang city of Sichuan Province after the Wenchuan earthquake,the predictive factors are determined by the seismic intensity of the dam site and the dam's performance before the earthquake,and a new projection index of fracture prediction of damaged earth-rock dam is put forward.The variable-order orthogonal Hermite polynomial is used to fit ridge function,and the simplex algorithm is used to optimize the projection index function.Then the projecti... |
