摘要
针对软岩料填筑面板堆石坝问题,基于邓肯E-B材料本构模型,结合鱼跳水电站混凝土面板堆石坝,拟定了三种不同的软岩料利用范围方案,运用大型有限元软件,进行了各方案坝体应力变形的有限元计算。结果表明:坝体及面板的应力变形对于软岩料的利用范围较为敏感;实际工程设计时,可在大坝应力变形可承受的范围内,尽可能地扩大软岩料的利用范围,使坝体断面设计既安全可靠,又经济合理。
Pointing to the problem of CFRD constructed with soft rock,based on the Dengken E-B constitutive material model and taken Yutiao CFRD as an example,the article protocolled the three different kinds of solutions by using the soft rock material and carried out the finite calculation of the dam＇s stress deformation by the large-scale finite element software.The results indicated that： The deformation and stress of the dam and face were sensitive to using range of soft rock.When designing actual engineering,we should expand the scope of using soft rock materials as much as possible within the dam＇s deformation and stress withstand and make the design of dam section more safe,reliable and economical.
