| Abstract: | Combined with the choice of the reasonable bridge type in the mountain areas and loess regions,the article collects the data and materials representing the substructure of the high-pier large-span continuous rigid frame bridge at home and abroad,puts forward the more accurate calcu- lating chart of the rigidity for the double-limb thin-wall pier,derives the horizontal displacement cal- culating formula of the pier top metered with geometric nonlinearity and the reasonable rigidity of the pier body,and discusses the relation of the double-limb centre distance with the stability. |

| Keywords: | reasonable bridge type applicability rigidity calculation reasonable rigidity with stability |
