| Abstract: | The mechanic characters of special-shape arch bridges and the contrast with the ordinary arch bridges are studied in this paper. Through numbering the examples, the variety law of special-shape arch bridge′s internal force is analyzed when the suspenders slope and the rise-span ratio are changed. In the light of t he analysis, some conclusions have been obtained. |
