【摘要】 在地震力作用下,许多在正常情况下稳定的边坡发生破坏。二级边坡作为常见的边坡形式,在该类边坡的施工设计中,地震力稳定性分析是非常重要的工作。基于极限上限定理,对地震力作用下的二级边坡进行了稳定性分析,为二级边坡的稳定性分析及设计提供了理论基础。并通过参数分析,研究了其临界高度随坡脚与水平地震系数的关系。更多还原

【Abstract】 Under earthquake force,some slope failures occur while the slope is stable under common condition.The slope with two-steps is often applied when construction and practical constraining,thus seismic stability analysis is an important job in design and construction.Based on upper bound theorem of limit analysis,the seismic stability of slope with two-steps is analyzed to provide a theoretical basis for studying the causes of instability and the reinforcement design.By parameter influence analysis,the variation of critical height with horizontal seismic coefficient and two slope angles is studied.更多还原
