摘要
运用有限元法与传统条分法相结合的方法对厦门市3处典型的近岸海床边坡进行了地震动力反应分析。在分析中，土体本构关系采用等效非线性模型，输入波为厦门市Ⅲ类场地的两个天然波和松潘地震波。分析结果表明：动力反应分析得到的安全系数小于相应的拟静力分析结果；3处边坡的最小安全系数均小于1。处于不稳定状态，需要加固处理。
Combining the finite dement method and slice method, earthquake response of several typical seabed sbpos in Xiamen was analyzed. Hardin-Drnevich model was used for the constitutive relationship of soil and two natural waves of Ⅲ kind of site in Xiamen and Song, pang-wave were used as input waves. The results show that all the minimum safety factors of these slopos are smaller than 1 and they are unstable. In addition, the minimum safety factor of dynamic response analysis is less than that of quasi-static analysis under the same condition.
