摘　　要：针对地铁二线设计强约束下自动设计的难点,提出一种负反馈线性转化求交法:首先对二线纵坡的所有约束进行数学刻画,推导出图形化求解方法;然后以此为理论基础,提出参照法初始化—常规约束调整—增强约束调整—负反馈检测与调整4阶段分治调整策略。该方法实现了规范几何常规约束与联合设置结构物等增强约束条件下的二线纵坡方案自动生成,以此研发的原型系统在厦门地铁等多条地铁线路设计中得到成功应用。该方法使设计人员摆脱了繁琐的二线纵坡调整过程,仅需对自动生成方案进行局部优化获得最终方案,设计效率大幅提升。Aiming at the difficulties in the automatic design under the enhanced constraints of the second-line design of the metro,in this study,a negative feedback linear transformation intersection method was proposed to automatically generate second-line longitudinal sections that satisfy all constraints.Firstly,all the constraints of the second-line vertical alignment are described mathematically,and a graphical solution method is derived.On the basis of this theory,a four-stage divide-and-conquer adjustment strategy was proposed:Initialization by reference method-Conventional constraints adjustment-Enhanced constraints adjustment-Negative feedbackdetection and adjustment. The automatic generation of second-line longitudinal scheme of alignment underconventional and enhanced constraints was realized with this method, and the prototype system has beensuccessfully applied in the design of Xiamen’s metro. Designers can get rid of the tedious slope adjustmentprocess and only need to carry out local optimization on the auto-generated scheme to obtain the final scheme,which improves the design efficiency greatly.
