鲤鱼潭大坝坝料动力参数反演
|
摘要
采用现行的室内外试验方法确定的土石料动力参数是否符合实际是人们关心的问题之一。提出了一种基于坝体加速度峰值和反应谱的土石坝坝料动力参数反演方法。利用鲤鱼潭大坝在集集地震中的加速度响应信息,反演了坝料的动力参数。结果表明,该方法是可行的,计算精度可满足实际工程要求。研究表明室内动三轴试验得到的坝料最大动剪模量系数K的值偏小,应予以修正。
Whether or not the dynamic parameters of earth rockfill determined in the laboratory or in situ are corresponding to the reality is a matter of concern. A back-analysis approach for the dynamic parameters of earth-rockfill based on response spectra and acceleration peak is presented. According to the acceleration response information of Liyutan Dam in the Chi-Chi earthquake, and by applying the back-calculation approach, the dynamic parameters are obtained. The results demonstrate that the proposed method is feasible, and the computational accuracy basically satisfies the practical engineering requirements. The dynamic shear modulus coefficient K of the dam materials obtained from the laboratory dynamic triaxial tests is small and should be revised.
