The genetic mechanism and evolvement process of the reservoir bank landslide were discussed detailedly based onengineering exploration and analyzing environmental geological conditions. And some main factors effecting stability of the landslidewere analyzed emphatically. Through building a 3D FEM model of landslide, the stable situations of the landslide under varioussituations were considered based on the strength reduction method. The result shows that the landslide is steady under the naturalsituation. The front edge of the landslide will be drowned out when the reservoir retains water normally; the safety factor reduces andcan’t meet the requirements of norms. The landslide tends to be more dangerous under rainfall infiltration and rapid drawdown of thereservoir water level. And the landslide will be instable when water storage situation and earthquake situation were considered at thesame time. According to the preceding analysis, the treatment measures of cutting slope and reducing load were presented. Thelandslide is steady under various conditions after being controlled. The relevant conclusions and methods proposed take a good effectin landslide treatment.

在利用有限元软件 ADINA 对预制钢筋混凝土箱涵结构进行滞回性能分析中,计算往往比较难收敛,而 ADINA 中提供的基于 Drucker-Prager 屈服条件、拉伸截断、帽盖硬化等准则的 Drucker-Prager Cap 模型,在对混凝土进行数 值分析时收敛容易,且计算速度较快,并通过比较,发现采用基于该模型建立的数值模型计算得到的滞回曲线与试 验得到的结果吻合程度较高,模拟结果较为准确。这一成果可以通过数值模拟的方式获得预制钢筋混凝土箱涵的 滞回曲线与相关数据,可应用于预制箱涵节段抗震计算和设计。
