基于汶川和芦山地震的沙牌坝址地震动输入研究
Study on earthquake ground motion inputs for Shapai arch dam based on Wenchuan and Lushan earthquakes
摘要
Abstract
Stochastic point-source and stochastic finite-fault methods were adopted to predict the strong motions at Shapai arch dam abutments during the Wenchuan earthquake according to parameters correction through repeated tentative computations from the records of strong motions observed at the station 051MXT during the Wenchuan earthquake and the records at Shapai arch dam abutments during the Lushan earthquake adopting the parameters of earthquake source,wave path and site effects,etc.provided by different researchers for these earthquakes.The results show that the simulated peak ground acceleration of accelerograms reaches 262 cm/S2 and the simulated amplification coefficient spectrum of average acceleration is close to the design response spectrum specified in "The specification for seismic design of hydraulic structures" for site class I0.关键词
