| Abstract: | The deformation of arch springs of hingeless arch has significant influence on the internal forces of arch bridge and the selection of proper arch seats to be built on the thick overburden layer ground is thus extremely important to reduce the deformation of the arch springs.In this paper,the considerations and general situations of arch seat type selection for design of Daning River Bridge are described,the mechanical analysis of two major types of the arch seats is made and consequently,the rational arch seat type is recommended in accordance with the results of the analysis. |
