摘　　要：介绍昆明机场线一期工程的概况,论述高架区间、单洞双线马蹄形隧道建筑限界设计及管线敷设。创新采用以直线地段单洞双线马蹄形隧道断面为基准,各曲线地段断面根据该曲线的参数计算的设备限界进行加宽的方法,整体上大大缩小了单洞双线马蹄形隧道断面面积,降低了工程投资。最后指出安全门等限界设计需综合考虑的因素。This paper introduces the general situation of the first phase project of Kunming Airport Rail Transit Line. It also discusses the construction clearance limit design and pipeline layout for the elevated area and for the single-hole double-track horseshoe-shaped tunnel. The innovation point is that： the cross-section at a straight line of the single-hole double-track horseshoe-shaped tunnel was taken as the benchmark, and then for each cross-section at a curved line, the facility clearance limit was widened after being calculated based on the parameters of this curved line. With this innovation method, the cross-section of this kind of tunnel was narrowed considerably and the project cost was reduced. At last,it introduces the safety door and other factors which should be considered comprehensively in clearance limit design.
