摘　　要：随着大直径盾构隧道施工的发展,为了便于管片运输,实现内部结构同步施工,互不干扰,将内部结构设计为箱涵拼装形式,从而节约工期,创造便利的施工条件。论文以某隧道箱涵施工为例,介绍了其施工组织设计和施工工艺,并对其拼装质量要求进行分析。With the development of large diameter shield tunnel construction, in order to facilitate segment transportation, realize the synchronous construction of internal structure, non-interference, the internal structure is designed as box culvert assembly form, thus saving the construction period and creating convenient construction conditions. Taking a tunnel box culvert construction as an example, this paper introduces its construction organization design and construction technology, and analyzes its assembling quality requirements.
