研究结论:客运专线无砟轨道施工平面控制网的坐标投影长度变形限定值应不大于10 mm/km;控制网沿线路应不大于5 km布设1对相距1km左右且相互通视的GPS点在GPS点之间布设近似直伸附和导线，导线边长400-600 m;任意3个相邻控制基桩点位误差引起的角度中误差应不大于8?? ?。

Abstract

Research purposes: The method of distributing plane control net and principles of precision design are presented in this paper through doing the researches on the design of plane control net for construction of ballastless track of passenger dedicated railway.

Research methods: By doing the simulation tests and making theoretical analysis of error, the inverse calculation was done for the precisions of control nets at all levels and the researches were done on the method of distributing control oat and the principle of precision design.

Research results: The method of distributing plane control net and principles of precision design are presented.

Research conclusions：The limitation value of long deformation of coordinate projection of the control net for construction of ballastless of passenger dedicated railway should not be over 10 mm/km. A pair of inter-visible GPS spots far away of approximate l km should be laid out within the range of S km along the railway fur the control net. The extending aux- diary facilities with approximate values and conducting wires should be installed between the GPS spots and the side length of the suite should be between 400-60D mm. The angle error caused by the error of any three adjacent control foundation pile spots should not he over 8 minutes.
