Newmark位移分析方法在海底斜坡地震稳定性评价中的应用
APPLICATION OF NEWMARK DISPLACEMENT ANALYSIS TO SEISMIC STABILITY EVALUATION OF SUBMARINE SLOPE
摘要
Abstract
Using the Newmark method for seismic time history analysis,we can put into account the effects of natural seismic peak ground acceleration (PGA),duration,and seismic frequency on seabed slopes,and different seismic waves can be input for simulation.In this paper,we calculated the dynamic response of a typical seabed slope as the Caofeidian to an earthquake similar to the Tangshan earthquake in scale.It is concluded that the value of displacement value can be used to quantitatively describe the influence of the earthquake on the slope.Therefore,the allowable displacement value of submarine slope and buildings on it can be used as a marker in security and stability analysis,which may provide important reference for slope stability evaluation and offshore construction.关键词
