| 摘 要： | 针对既有隧道改建为城市轨道交通线路的具体实践，建立以线路平面和纵断面设计控制点为约束条件，改建量平方和最小为目标函数，采用拉格朗日乘子法进行优化设计的方法，初步确定线路位置；建立线路贯通性与限界适应性分析的指标体系，并以此为基础，编制限界自动分析软件，确定最佳的线路设计位置，从而解决了既有隧道工程改用作城市轨道交通线路时线路贯通性和限界适应性的分析问题.

| Abstract: | Based on the practice of using existing tunnel as urban mass transit alignment, a mathematic model is established. Some restrictive conditions in the alignment design process of the plan and profile are considered, the least sum of square reconstruction labor is regarded as the objective function and this nonlinear programming problem is solved by Lagrange multiplier method, then the alignment location is initialized; By establishing proper evaluation index system for alignment and clearance analysis and programming on clearance analysis automation, the optimized alignment is determined, so the analysis problem of alignment design and clearance adaptability are solved successfully while using ex- isting tunnel as urban mass transit. |
