Abstract
The technology of using a reinforced yoke to strengthen arch bridge is newly
developed by the author of the present paper. Application of the technology to
five bridges as well as a series of mode experiments have seen desired results. In
light with the fracture mechanical theory, the paper discusses the role of the said
technology in keeping the arch bridge cracks from further developing and in
bettering the forcing property of bridge. The mechanical computation mode of
the new technology is thereupon proposed. The views presented in the paper are
expected to help improve the existing theory about bridge strengthening.
1 Introduction
As known to all, the safety of vehicle transport requires the bridges to have
enough bearing capability, and in the present world, a certain numbe
