Abstract: Concerning Ansha Dam’s 3# section’s relatively poor geological condition, peculiar cross-section shape relatively large annual variation arrange of crest-horizontal-displacement, analysis based on thin-layer-unit FEM is carried out, concrete integrated elastic-modulus is calculated, compound model is set up, and calculation of intensity and stability is performed, which concluded that the 3# section’s structure and working state is normal and provides reference for dam safety operation.?

摘要: 本文针对安砂大坝3#坝段基岩地质条件较差、建基面形状特殊、坝顶水平位移年变幅较大等情况,对其进行薄层单元有限元分析,反演坝体综合弹性模量,建立混合模型,进行强度和稳定校核,得出3#坝段结构与工作性态正常的结论,为大坝的安全运行提供了依据。
