某跨海大桥建设秉承“大型化、工厂化、标准化、装配化”的设计理念，其非通航孔的承台、墩身均采用在预制工厂集中预制的方案进行施工。通过研究提出了非通航孔桥承台、墩身可行的预制方案，并对各种预制方案存在的关键技术问题进行分析，在此基础上，从预制匹配精度控制、工厂化预制实施、混凝土浇筑、预制场内运输、出运方式以及对后续施工的影响等方面综合对比分析各种方案的优缺点，提出最优的墩台工厂化预制方案。

The sea-crossing bridge construction takes the design idea of maximization, the factorization, the standardization and the assembly, the pile caps and pier shafts of the non-navigable span are prefabricated at the factory. In this paper, the prefabrication solutions are put forward to pile caps and pier shafts of the non-navigable span, and the key technical problems of all kinds of prefabrication solutions are analyzed. On this basis, the optimal pier factory prefabrication is proposed by the comparison of various schemes, which is carried out about advantages and disadvantages of prefabricated matching accuracy control, industrialized prefabrication, concrete placing, transportation in the prefabrication yard, transportation style and the impact on follow-up construction. Finally,the optimum scheme of industrialized prefabrication for pier and abutment is proposed.
