水荷载引起混凝土重力坝位移的理论研究

THEORETICAL STUDY ON CONCRETE GRAVITY DAM'S DISPLACEMENT WITH WATER LOAD

  • 摘要: 基于多孔连续介质模型,从理论上探讨了作用在地基上的水荷载作为渗流体荷载时引起混凝土重力坝的位移,导出了均质各向同性地基在渗流体荷载作用下的应力解答和位移解答.通过理论分析得到:(1)由于渗流体荷载引起上游地基下沉,下游地基上抬,从而使地基转动,导致坝体向上游位移. (2)作用在地基上的水荷载按面荷载分析的位移大于按渗流体荷载分析的位移,但它们都引起坝体向上游位移.

     

    Abstract: The concrete gravity dam's displacement caused byfoundation seepage volume forces was studied based on the elastic theoryand aporous continuum model. Stresses and displacements in the isotropicfoundation with seepage volume forces are obtained. Some conclusions aredrawn: (1) With the upstream foundation subsidence and the downstreamfoundation elevation by the seepage volume forces, the dam has an upcurrentdisplacement. (2) The displacement caused by the foundation area force islarger than that cansed by the foundation seepage volume force, but these loads alllead to the dam upcurrent displacement.
