摘要:
对西南强震区某拟建覆盖层上高面板堆石坝进行不同超越概率地震波作用下的地震反应计算分析,重点研究大坝在强震作用下动位移、加速度,面板动应力及坝基覆盖层液化等地震反应特性.研究表明:随着输入地震波峰值的增大,大坝动位移和加速度、面板动应力,覆盖层动孔压和液化度等反应均逐渐增大,但加速度放大倍数逐渐减小.在100年超越概率2%的校核地震作用下,大坝的抗震安全性依然在合理范围之内,大坝的抗震设计是合理的.
Abstract:
The calculation of dynamic response and seismic safety evaluation of a high CFRD on alluvium de-posit subjected to seismic excitation of different transcendental probabilities were carried out,with emphasis onthe seismic response characteristics of dynamic displacement,acceleration,dynamic stresses of face slab andliquefaction of alluvium deposit under strong excitation. The results show that dynamic displacement,accelera-tion,dynamic stresses of face slab and liquefaction degree of alluvium deposit will increase gradually with theincreasing of seismic wave peak ,but the acceleration magnification will decrease.The seismic safety of dam isstill within a normal range even for transcendental probability 2% in 100 years.
