结合南水北调中线工程中倒虹吸闸室段的闸门结构复杂、放样较困难的特点，通过分析自由放样方法的原理及放样点位精度，提出了利用自由设站方法对弧形闸门特殊结构牛腿及支铰中心的放样，同时也简单论述了侧轨及底坎的放样方法。工程实例表明：放样方法不仅在理论上满足放样精度要求，而且在实际工程中也可达到规范要求。

According to the complicated structure and lofting difficulty for the radial gate of the inverted siphon in Medi -an-Line South-to-North Water Transfer Project ,and through analyzing the principle of free lofting method and positional lofting accuracy ,the free-station method is proposed for lofting the bracket and hinge center of radial gate ,then the loft-ing methods for the side rail and bottom sill are simply discussed .Combining with the practical examples of Median-Line South-to-North Water Transfer Project ,it is proved that the lofting method could not only satisfy the equirements of lofting precision in theory ,and also meet the specification requirements in practical engineerings .
