The Estimation of the Precision of the Control Network of Bridge Construction

This paper probes into the precision estimation of the control network of the bridge construction, puts forward the suggestion of using the precision of the location of pier as the precision for the design of the control network, and points out that should be on the basis of designed control network, bridge design drawings and construction layout method for each pier, and adopt indirect error compensation model to calculate the precision of pier layout, which can be used as the reference for the design of the precision of bridge control network and the precision analysis.
