新疆某水库大坝三维应力有限元分析OA

The reservoir dam investigated in this study is an asphalt concrete core gravel-sandfill dam,with extensive colluvial deposits distributed along both riverbanks at the dam site.To address challenges including insufficient material sources,limited project investment,and high seismic performance requirements,an innovative scheme was proposed to reuse local natural colluvial materials as secondary rockfill materials.Based on field exploration,sampling,laboratory and in-situ testing,and three-dimensional finite element analysis,the mechanical behavior of the dam body was systematically evaluated.The results demonstrate that the proposed scheme satisfies the stress-deformation requirements while significantly reducing construction costs.This paper elaborates on material properties,finite element model establishment,static analysis results,and engineering optimization recommendations,providing a valuable reference for similar dam projects.
