摘　　要：就互通立交匝道半径小、结构物较多的特点,介绍了施工测量控制原则,提出了从整体控制测量到局部极坐标放样的施工测量控制方法,该方法不仅操作简便、准确,而且质量可靠、效果好,保证了立交区匝道的设计线型。According to the features of interchange, such as small radius of ramp and more structures principle is introduced for construction survey and control as well as practical method from whole survey to local point setting by polar method. Practice shows this method is simple, convenient with good effect, which ensures designed line of interchange ramp.
