摘要
目前盾构隧道内部结构施工基本属于半预制化阶段,许多构件仍采用现浇形式。建设效率低,能耗高,施工慢,产生较多建筑垃圾、对环境污染大,同时局限于盾构隧道有限的施工空间及现场工人的素质,施工质量难以保证。为了实现快速施工、绿色施工,盾构隧道内部结构走向预制化、工业化的道路。通过对比现浇结构受力模型及特点,分析各种盾构隧道预制双层车道结构体系的受力特征及特点。
At present, the structural construction in the shield tunnel basically belongs to the semi-prefabrication phase. Many components are all casted in site. The construction efficiency is low, the energy consumption is high, the construction is slow, more construction waste is produced, the environmental pollution is large, and also it is limited in the limited construction space of shield tunnel and the quality of field workers. The construction quality is hard to guarantee. In order to realize the rapid construction and the green construction, the internal structure of shield tunnel will be prefabricated and industrialized. According to the comparison of the stress models and characteristics of cast-in-situ structure,the article analyzes the stress features and characteristics of various shield tunnel prefabricated double-layer lane structure systems.
