| Abstract: | In the light of large - scale tunnel and water - carriage engineering of Dahuofang Reservoir, the paper introduces the design thinkings of control system for construction measurement as well as the estimation for the errors in transverse, longitudinal and vertical throughs of tunnel, which were aroused by the errors of control system design. The predicted result accuracy illustrates that present design scheme could satisfy requirements for control of errors in transverse, longitudinal and vertical throughs. |
