Detection Technology of Effective Prestress under Anchorin in Urban Bridge Construction
Taking the prestressed construction project of the second standard bridge on the south extension line of Changtian Road in Haikou as an example,this paper introduces the detection technology of effective prestress under anchor of urban bridge.The technology mainly through the installation of sensors under the anchor,real-time monitoring of the stress of the prestressed tendons,timely detection and solution of potential safety hazards,to avoid the damage of the bridge structure due to improper stress control of the prestressed tendons,to ensure the quality and safety of urban bridge construction.The conclusion shows that the test technology of effective pre-stress under anchor,comparing the design and actual data,provides data support for the test of prestress,which is conducive to the maintenance and repair of the bridge,and thus reduces the maintenance cost.
