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。
Under earthquake force, some slope failures occur while the slope is stable under com- mon 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 theo- rem of limit analysis, the seismic stability of slope with two - steps is analyzed to provide a theoretical ba- sis 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.
