摘　　要：为进一步优化辽阳葠窝水库除险加固工程挡水坝段锚索设计方案,通过使用Midas GTS NX软件对该工程23号挡水坝段原坝体、坝体施工缝和纵缝、锚索及下游新浇筑坝面混凝土进行组合建模,分析在正常、设计及校核水位下,施加预应力锚索对坝体内应力分布情况的影响。结果表明:锚索使上游坝面的压应力增大约10%,对下游面的应力及坝体内应力改变几乎没有影响。研究成果有效解决了坝踵拉应力问题,对同类型工程具有一定的借鉴意义。To further optimize the cable anchor design for the water-retaining dam section of Shenwo Reservoir risk elimination and reinforcement project in Liaoyang City,by employing Midas GTS NX software,a composite numerical model was established for the original dam body,construction joints,longitudinal joints,cable anchors,and the newly cast downstream concrete face of No.23 dam section.The analysis evaluated the effects of prestressed cable anchors on stress distribution within the dam under normal,design,and check water levels.The results indicated that the cable anchors increased compressive stress at upstream dam face by approximately 10%,while exerting negligible influence on stress and internal stress redistribution at downstream dam face.The findings effectively resolved tensile stress issues at the dam heel and can provide a references for similar engineering projects.
