Background： The Daya Bay neutrino experiment is designed to measure the mixing angle 013 using anti-neutrinos produced by the reactors of the Daya Bay Nuclear Power Plant （NPP） and the Ling Ao NPR The distance from nuclear reactors to experiment detectors is needed. Purpose： The aim is to introduce the way of building and measuring the control network during the distance surveying. Methods： The 3D distance was obtained by GPS, total station and laser tracker, and several software and different instruments were used for the combination of data adjustment and coordinate transformation, as well as the correctness checking. Results： Through the actual measurement and data processing, the accuracy of the distance is better than the designed requirement of ±40 ram. Conclusion： The success of the Daya Bay reactor neutrino experiment demonstrates that the result of 3D distance measurement is reasonable and correct, and the survey work makes an important contr
