覆盖层上高面板堆石坝的极限抗震能力
Maximum seismic capacity of a high concrete-face rockfill dam on alluvium deposit
摘要
Abstract
In consideration of the dynamic response of a concrete-face rockfill dam ( CFRD) to earthquakes, the calculation method and evaluation standards for seismic damage to CFRDs are investigated from the aspects of the seismic stability of dam slope, permanent deformation of dam body after earthquakes, liquefaction of foundation overburden, and deformation of slab joints of the CFRD. The maximum seismic capacity of a 135 m CFRD on an alluvium deposit is calculated using the three-dimensional finite element method. Result analysis shows that the dam has strong earthquake resistance, with a maximum seismic capacity of about 0. 52g to 0. 54g.关键词
