摘要
线路控制测量的作用是为后续工程的顺利进行做好基础工作,在特殊地区需要采用特殊方法。在安林高速公路二号线修建过程中,采用了"双控制点"法布设控制点,取得了理想的效果;通过平差计算,证明该方法的精度是可靠的,在工程中是切实可行的。
The role of Line Control Survey is to fulfill the basic work for a smooth implement of the followup project. Special methods should be taken in specific areas. In building Line 2 of Anlin freeway, the method of ＂dual-control point＂ was adopted, which achieved a desired result. Accuracy of the method is proved reliable through adjustment calculation. It is practicable in engineering.
