Abstract:
Author researched and explored the techniques and measures to reduce vibration of high-speed train bridges from the viewpoint of structure engineering, such as applying prestressing techniques to control micro deflection of bridges; doing well design of PC box beam to resolve skew cracking and deflection problems; adopting external prestressing techniques to improve structure stiffness of bridges; adopting outside wrapping CFRP column techniques to enhance aseismatic ability of piers; exploring the theories of intelligent prestressing theory in bridge structures. Moreover, author also put forward using ALC slabs to build noise barrier in order to eliminate noise. Finally, innovation research and engineering practice of a concrete cable-stayed bridge with CFRP cables were briefly introduced.
