摘　　要：针对目前盾构排布算法在缓和曲线段偏移方面存在的不足,借助Dynamo可视化编程工具,从设计图纸提取关键数据,利用离散化处理后重新拟合的思路,确定空间理论隧道中心线。建立算法实现盾构区间衬砌的快速排布,通过工程实践偏差统计验证,确定该方法实现的模型精度能够满足工程精确化要求。Focused on the current deficiencies of the shield arrangement algorithm in easing the offset of the curve segment,this paper uses the Dynamo visual programming tool,extracts the key data from the design drawings,and uses the idea of refitting after discretization to determine the spatial theoretical tunnel center line.The paper establishes an algorithm to realize the rapid arrangement of tunnel linings,and through the statistical verification of deviations in engineering practice,it is determined that the model accuracy achieved by this method can meet the requirements of engineering accuracy.
