中文摘要：

为了评估清水池的地震破坏状态，基于海城地震、唐山地震中较详细的水池震害资料，分析了水池的主要震害现象、特征，并找出了影响水池震害的主要因素。采用最小二乘法对震害数据进行回归分析，得到了各震害影响因素不同情况下的回归系数取值，从而建立了清水池震害经验统计回归模型。经计算该模型的相关系数为0．661，标准差为0．447。经回判分析，模型回判成功率为91．2％。对于模型中未考虑到的震害影响因素，根据实际震害经验，给出新增影响因素的建议系数。对汶川、玉树等地震中遭到破坏的清水池进行评估，结果与实际震害基本相符，初步验证了该评估模型的可靠性。

英文摘要：

In order to assess the seismic quake damage data of clean water tanks damage of clean water tanks, based on the detailed earth- from Haicheng earthquake and Tangshan earthquake, the phenomena and characteristics of clean water tanks subjected to earthquake damage are analyzed and the main influence factors are found. The least square method is used in the regression analysis of the earthquake damage data to obtained the regression damage under different conditions and to establish an coefficients of influence factors of earthquake empirical model to evaluate the earthquake damage of clean water tanks. The correlation coefficient of the model is 0. 661 and the standard de- viation is 0. 447. The model has an accuracy of 91.2% by the regression discriminant analysis. Ac- cording to the earthquake experience, the adjustment coefficients for new influence factors that are not considered in the model are given. Evaluation results are consistent with the actual damage to the clean water tanks in Wenchuan earthquake and Yushu earthquake, and etc. Thus, the model is preliminarily proved to be reliable.
