广东伶仃洋跨海大桥非通航孔桥桥型采用８０ｍ、５０ｍ跨预应力混凝土箱梁预制，安装先简支后连续的设计、施工方案，通过对设计方案的介绍，指出简支转连续梁桥在规模宏大的非通航孔桥桥型方案比选中的可行性与优越性。特别是８０ｍ跨等截面简支转连续箱梁桥的设计与施工在国内尚属首创，许多问题应进一步加以研究、探讨。
The non-navigable bridge bridge of Lingdingyang Sea-crossing Bridge in Guangdong is prefabricated with prestressed concrete beams of 80m in length and 50m in span. The design and construction plan of the prestressed concrete box girder is first installed. After introducing the design scheme, it is pointed out that the simple supported continuous girder bridge In the large-scale non-navigable bridge type scheme comparison and feasibility of the choice. In particular, the design and construction of the 80m-span simply-supported continuous box girder bridge is still the first in China, and many problems should be further studied and discussed.
