摘要
以某大跨度6连拱式水利渡槽为分析对象,利用堆载试验和仿真计算2种方法对其钢管立柱与贝雷梁组合拱架在施工中的变形进行分析。得出钢管立柱与贝雷梁拱架系统的弹性变形及非弹性变形规律,并通过对比分析得到拱架底模系统在施工中的变形规律,为该渡槽后续施工提供技术指导。
With some large-span 6 multiple arch water conservancy aqueduct as analysis object, this paper analyzes deformation of combined arch frame of steel tube column and Bailey beam in construction by means of surcharge load test and simulating calculation to obtain the laws of elastic deformation and non- elastic deformation of arch frame system of steel tube column and Bailey beam, and obtains deformation laws of bottom die system of arch frame in construction via comparative analysis to provide technical guidance for subsequent construction of the aqueduct.
