| 摘 要： | 本文建立了计算土边坡地震反应及评价其动力稳定性的一个数值分析模型，将上边坡在动力作用下的应力状态简化为自重应力状态和附加动力状态的叠加，并对这两个应力状态分别进行研究。本文用时域集中质量显式有限元方法结合多次透射公式，研究了无限域中边坡在动力作用下的位移场和应力场，提出了土边坡动力稳定性的定量评价方法。 |
| 关 键 词： | 土边坡 动力稳定性 显式有限元 多次透射公式 地震反应 位移场 应力场 |

| Abstract: | In this paper the model of numerical simulation for calculating seismic response and dynamic stability of soil slopes is proposed. The general stress field of slopes under earthquake loading may be considered to be the superposition of gravitational stress field and the additional dynamic stress. field. Then the two stress fields may be studied independently of each other. The displacements and stresses of soil slopes of unbounded region are calculated by the method of lumped-mass explicit finite element and multi-transmitting formula. The quantitative evaluation method of dynamic stability of soil slopes is proposed. |
| Keywords: | soil slope dynamic stability explicit finite element multi-transmitting formula |
