摘要

为了快速准确地对遭受地震影响的土坝工程的破坏状态进行评估，以土坝震害经验统计判断模型为基础，选取了更为合理的土坝震害影响因素，采用最小二乘法重新对土坝震害数据资料进行回归分析，得到了各震害影响因素在不同条件下的回归系数取值，从而建立了一个改进的土坝震害经验统计判断模型。与原模型相比，改进模型既剔除了不合理的震害影响因子，同时又使回归模型的预测准确度得到提高，其相关系数为0.908，标准差为0.459，均比原模型要好。采用两种模型对汶川地震中遭到破坏的47座土坝进行震害评估，并与实际震害进行了对比分析，初步验证了改进模型的可靠性

Abstract

In order to evaluate earthquake damage to earth dams quickly and accurately

more rational influence factors of the damage are chosen based on the empirical model. The least square method is used to re-analyze the earthquake damage data of earth dams. The regression coefficients of the influence factors of earthquake damage under different conditions are presented; and an improved empirical model to evaluate the earthquake damage to earth dams is set up. In the new model

irrational influence factors are eliminated; and the prediction accuracy of the regression model is improved with the correlation coefficient of 0.908 and the standard deviation of 0.459

which are better than the original model. By using both the improved and original model

47 earth dams damaged in Wenchuan Earthquake are evaluated. The results are analyzed by comparing with the real seismic damages

preliminarily proving the improved model to be more satisfying.
