摘　　要：为探索锚固梁宽度、锚固梁高度、锚拉筋长度、锚固板长度、泄洪量以及堰顶插筋长度等因素对溢流面坝身变形的影响,采用正交设计方法,依托在建工程松树林水库,采用非线性弹性模型(邓肯E-B模型)确定溢流面坝身变形,通过极差分析,确定各因素对溢流式面板堆石坝溢流面坝身变形的敏感性。结果表明,堰顶插筋长度对变形量的影响最大;锚固板长度对变形量的影响最小。In order to explore the influence of anchorage beam width,anchorage beam height,anchorage bar length,anchorage plate length,flood discharge capacity and weir top joint bar length on the deformation of overflow surface dam body,the orthogonal design method is adopted,the nonlinear elastic model(Duncan E-B model)is adopted to determine the deformation of overflow surface dam body relying on the Songshulin reservoir under construction,and the range analysis is adopted to determine the influence of each factor on overflow surface dam body.The results show that the length of the joint bar on the top of the weir has the greatest influence on the deformation,and the length of the anchor plate has the least influence on the deformation.
