Abstract

Partially assembled structures were used replace earth-retaining struts during construction of a prefabricated subway station on the Shenzhen Metro in China. A three-dimensional numerical model was developed to investigate the interaction between the Pingxi Station structure and the earth-retaining system for different assembly sequences. The results showed that the prefabricated structure performed satisfactorily during construction, and the sequence of assembly had a significant influence on the distribution of internal forces and stresses, especially in the substructure. The analytical approach applied here can be extended to assess other prefabricated underground structures.

预制地铁站施工过程中的三维分析

在中国深圳地铁预制地铁站的施工过程中，使用了部分组装结构来替代挡土支撑。建立了一个三维数值模型，以研究平溪站结构与不同组装顺序的挡土系统之间的相互作用。结果表明，预制结构在施工过程中表现令人满意，组装顺序对内力和应力的分布，尤其是下部结构的内力和应力的分布有很大影响。本文采用的分析方法可扩展用于评估其他预制地下结构。

期刊介绍： Civil Engineering, listed by the Web of Science, is the ICE''s flagship journal. Practical and diverse in its scope, it publishes overview papers for the non-specialist on any subject relevant to civil engineering today. Topics range from landmark projects to philosophical, ethical, environmental, management and safety issues. Peer review, copyediting, and colour publication by Civil Engineering are free. If accepted, published papers are easily found by Google search, as well as in specialist citation indexes. There is also the option of making your article open access, should you wish to. Published authors receive a free electronic copy of their article to share with their peers. Furthermore, as well exposure to ICE''s 91,000-strong membership, published papers are promoted via our social media channels, accessing the wider civil engineering community. It is free to submit a paper to this journal. Papers appear Ahead of Print (below) as soon as they are ready to be published. Ahead of print articles are fully citable. using the DOI system
