| Abstract: | Taking Heixi Expressway Tongshanxi River Bridge of Fujian as the engineering background,the long-time down-warping problem,down-warping property and structural performance of high-pier long-span continuous rigid-frame bridge are studied.A long-acting monitoring method of high-pier long-span continuous rigid-frame bridge is put forward to guarantee the safety,integrity,applicability and durability of operating Tongshanxi River Bridge,which provides the theoretical and technical support for the long-time use and further application of long-span pre-stressed concrete girder bridges. |
