| Abstract: | No.1 bridge in highway of the Connection Works of YRDP is a fabricated and prestressed hollow deck one,in which some parts of hollow plate occurred crack in varying degree.In this paper,the cause why crack occurred is analysed,verifying that it is chiefly to the unfit temperature control in course of pouring and curing of concrete,the too short curing time and the deformation of abutmen foundation. |
