摘要
Newmark滑块分析法是评价边坡地震稳定性的一种实用方法,已广泛应用于边坡地震永久位移的计算中。主要针对近几十年来Newmark滑块分析法的发展及应用进行回顾,包括传统的Newmark刚塑性滑块法、Makdisi-Seed法、简化地震位移法、Bray-Travasarou概率分析法、耦合多滑块Newmark法和振动台模型试验,并进行简要论述,指出上述方法存在的问题和今后的发展方向。
Newmark sliding block analyses represent a useful and practical tool for evaluation of seismic slope stability hazards and are widely used for estimation of permanent displacements of rock-soil slopes in earthquakes. The development of Newmark sliding block analyses in recent decades are briefly reviewed in this paper. The method include the conventional Newmark model,Makdisi-Seed model,Bray( 1998) simplified seismic displacement model,Bray-Travasarou( 2007) simplified seismic displacement model based on the theory of probability,modified couple Newmark model and shaking-table model test. Some concise remarks are made. Then,existing problems are pointed out and the study problems,which need to be done in future,are suggested.
