| 摘 要： | 针对土石坝在蓄水过程中应力场与渗流场间的耦合问题,基于ABAQUS平台,建构了可考虑土体非饱和特性的均质土坝的有限元计算模型,并数值模拟了蓄水过程中土坝渗流场和应力,获得了土坝的渗流、应力及变形的相关规律。结果表明,该方法操作简便,可行、有效。

| Abstract: | In order to solve the problem of the coupling effect on stress field and seepage field during impoundment of reservoir with the earth rock dam,based on the platform of ABAQUS,finite element analysis model of homogeneous earth dam is set up with considering the unsaturated soil properties.And then using this analysis model to examine the seepage field and stress field of the dam during reservoir impounding process,some relevant rules on seepage field,stress field and deformation are obtained with numerical s... |
