| Abstract: | The paper introduces the posttensioning prestress used in the bridge engineering giving some engineering instance. It mainly consists of the construction and quality control of the key working procedure-setting up pore canal, reinforcing steel bar passing through, grouting ,etc. and the theoretical computation method of the extension value of the jack piston. All of these ensure that the structure meet the demands of the criterions. |
