某碾压混凝土坝层面应力及渗流分析

Stress and Seepage Analysis of Layer Faces for Roller Compacted Concrete Dam

对某碾压混凝土坝施工层面进行应力和渗流有限元分析,获得正常蓄水条件下碾压混凝土坝层的最大剪应力、最大总应力分布规律层面渗流量和最大渗透坡降。结果表明,施工层面是碾压混凝土坝渗流的主要通道,若对其处理不当会严重威胁大坝的安全运行。

Using finite element approach, this paper analyzes the stress and seepage of layer faces for a roller compacted concrete dam. The maximum shear stress, the maximum total stress distributions, and the seepage volume and the maximum gradient of the layer faces for the RCC dam under normal water storage condition are obtained. The results indicate that the layer faces are the main seepage channels of the RCC dam, which can seriously threaten the safe operation of the dam if the layer faces are not properly handled by effective measures.
