| 摘 要： | 地铁线路限界设计是保证地铁车辆安全运行的关键技术。合理精确的限界设计可以减少土建投资，节约成本。其中，相对于直线地段，曲线地段的限界加宽量计算相对复杂，方法也不尽相同。通过分析地铁车辆在圆曲线、缓和曲线以及曲线过渡段的限界加宽量，利用MATLAB编写相应的程序，进一步简化地铁线路曲线地段限界的计算。

| Abstract: | Gauge is the key technology to ensuring the safe operation of metro vehicles. In addition, reasonable and accurate gauge can reduce the investment. Compared to a straight-line section, the calculation of the gauge widening in a curved section is relatively complicated, and the methods are different. By analyzing the clearance widening of a metro vehicle in a circular curve and transition curve, a corresponding program was made using MATLAB to simplify gauge calculation. |
