| 摘 要： | 采用弹塑性块体单元法计算三峡大坝左岸３＃厂房坝段及地基的位移场和应力场，并根据位移突变和屈服区连通两类失稳判据确定其强度储备安全系数。此外，对地基内结构面具有不同连通率的情况进行了稳定性分析。

| Abstract: | The displacement and stress fields of dam section No.3 and its foundation of the Three Gorges Project are computed with elasto plastic Block Element Method(BKEM).The safety coefficient is determined with two unequilibrium criteria of abrupt displacement enlargement and yielded area connection.Stability analysis for different connection rates of structure interface in the foundation is also presented. |
