摘　　要：为了加深对组合梁桥的认识,提高桥梁设计技术,更好地理解和完善相关规范,针对刚果(布)1号公路二期工程Djoué组合梁桥,需要对其进行整体优化以节约用材并提高承载性能。采用ANSYS软件分别进行了桥型优化,混凝土板厚度优化和钢梁高度优化。选定了钢-混凝土组合梁桥桥型并确定了混凝土板厚度和钢梁高度。这为Djoué大桥的施工,组合桥梁的后续研究和相关规范的完善提供了技术参考。In order to learn more about the steel - concrete composite bridge which the Djoue bridge in the second stage of the I st national road project in Congo（Brazzaville） has selected ,promote the design technologies of bridges and better understand and improve the relevant standards, the overall optimization design analysis of Djoue Bridge aiming at saving steel and improving bearing capacity is necessa- ry. ANSYS is used in optimization of bridge type, concrete thickness and height of steel beam. It can pro- vide technical references for the construction of the Djoue Bridge, the follow - up study of the steel - con- crete composite bridge and the specification improvement.
