摘　　要：为更好地降低桥梁工程成本,提高桥梁钢筋的使用率,提高其加工制造的智能化程度,在BIM模型基础上,提出了以整数线性规划和Monte Carlo模型为基础的钢筋下料的优化模型及方法。依托阳新高速公路黄河特大桥工程,用软件建立三维钢筋普通模型,实现了对数据的自动提取,能够自动而批量化地获取钢筋数量及尺寸等属性。通过处理钢筋的根数及长度,初步构建了钢筋剪裁方案,并按照工程要求,以整数线性规划法组合优化了该剪裁方案,选出了钢筋使用总量最少的下料优化方法,钢筋优化率达到19.55%。In order to reduce the cost of bridge engineering,improve the usage rate of bridge reinforcement and the intelligentized degree of its manufacture,based on the BIM model,based on the Integer Linear Programming(ILP)and Monte Carlo model,an optimization model and method for steel blanking are proposed.Based on the Yellow River Bridge project of Yangxin Expressway,a 3D steel bar model is built with software,which can automatically extract the data and obtain the quantity and size of steel bar in batches.By dealing with the number and length of reinforcing steel bar,the cutting scheme of reinforcing steel bar is preliminarily constructed and optimized by the method of Integer Linear Programming according to the requirements of engineering,the optimization method of steel bar cutting with the least total amount of steel bar is selected,and the optimization rate of steel bar cutting reaches 19.55%.
