地下空间结构预制拼装技术综述

Overview of Prefabricated Assembly Technology of Underground Space Structure

随着城市建设的发展,如何解决地下工程建设中的速度、质量、效益问题成为人们关注的焦点。地下空间结构采用预制拼装技术是提高工程质量、缩短工期、节省造价的有效方法。在论述地下预制拼装特点及发展趋势的基础上,介绍盾构圆形隧道预制拼装式衬砌结构、明挖法公路和铁路隧道拼装结构、明挖地铁车站预制拼装结构、明挖综合管沟预制拼装结构和微型地下智能停车库预制拼装结构等几种主要地下预制拼装结构,以供类似工程参考借鉴。

With the development of urban construction,how to solve the problems of speed,quality and benefit in the underground engineering construction has become the focus for attention.The prefabricated assembly technology used for the underground space structure is the effective method to improve the engineering quality,to shorten the construction period,and to save the construction cost.This article firstly discusses the underground prefabricated assembly characteristics and the development tendency,then introduces several main underground prefabricated assemble structures of the prefabricated assembly lining structure of the shield circular tunnel,the assembly structure of excavated highway and railway tunnel,the prefabricated assembly structure of excavated subway station,the prefabricated assembly structure of excavated municipal pipeline tunnel and the prefabricated assembly structure of miniature intellective underground garage,which can be referred for the similar projects.
