Measurement Techniques of Reference Line for Anchor System of North Anchorage of a Bridge

Abstract

As an important force part of the Bridge, the precise positioning of the construction of anchorage system is especially important. Combining with the practice of bridge engineering, this paper introduces the precise positioning of anchorage system by two-point reference line lofting principle. The results have proved that all the deviations satisfy the requirements of regulation by reference line lofting. This method decreases the cost, increases the measuring accuracy. It is worth wide spreading.
