进行了600 m跨径的高强混凝土（ HSC）拱桥和活性粉末混凝土（ RPC）拱桥的试设计，利用MIDAS软件建立空间有限元模型进行内力计算，依据公路圬工桥涵设计规范（ JTG D61—2005）对RPC拱桥进行强度与稳定的验算。从拱圈截面刚度、内力与稳定和工程数量等方面，对这两种拱桥的受力性能和施工性能进行比较，分析RPC在超大跨径混凝土拱桥上应用的可行性，为我国拱桥向超大跨径发展提供参考。
進行瞭600 m跨徑的高彊混凝土（ HSC）拱橋和活性粉末混凝土（ RPC）拱橋的試設計，利用MIDAS軟件建立空間有限元模型進行內力計算，依據公路杇工橋涵設計規範（ JTG D61—2005）對RPC拱橋進行彊度與穩定的驗算。從拱圈截麵剛度、內力與穩定和工程數量等方麵，對這兩種拱橋的受力性能和施工性能進行比較，分析RPC在超大跨徑混凝土拱橋上應用的可行性，為我國拱橋嚮超大跨徑髮展提供參攷。

Two trial designs of High Strength Concrete( HSC ) arch bridge and Reactive Powder Concrete (RPC)arch bridge with 600m span were carried out. Internal force was calculated in the finite element model, which was established by MIDAS software. The strength and stability of RPC arch was checKed in accordance with Code for Design of Highway Masonry Bridges and Culverts( JTG D61-2005 ). The mechanical property and worK-ability of these two Kinds of bridges was compared in terms of arch section stiffness,internal force and stability and quantities of bridges,etc. The feasibility of the RPC’s application on super long span arch bridge was analyzed. It will provide information for the further development of China’s super long span arch bridge.
