Measuring and Analysis of Local Stress under Anchorage of Continuous Rigid Frame Bridge
Under the Large Tonnage Pre-Stress, the stress of concrete which is under the anchor plate is complicated. To ensure the safety of construction and structure, the condition of local stress of the bridge structure should be investigated. When the pre-stress steel of Segment 1# of Pier 1# of Hongwuwo Bridge is tensioned, the strain situation of concrete near the anchor plate of the box girder is measured. The measured value is compared with the analytical value which is obtained through space finite element method.
