城市隧道半敞开段结构受力分析

Force Analysis of Semi-open Section Structure of Urban Tunnel

摘要:

城市隧道设置一定长度的半敞开段，能显著改善隧道内的通风、照明及视觉效果，提高行车的安全性和舒适性，但顶板开洞使隧道结构的受力变得复杂。以郑州市某隧道为例，建立三维空间板壳模型，通过对顶板是否开洞，以及开洞后不同横梁布置情况下的隧道结构进行比较分析，探讨隧道半敞开段结构受力特性，得出一些结论，可供相似工程参考。

Abstract:

In order to study the application technology of BIM technology in the full life-cycle management of road infrastructure, relying on Suzhou - Wuxi - Changzhou Southern Expressway Project, a BIM technology is used to carry out the comprehensive management and control of the full life-cycle information of important projects such as underwater tunnel and hub interconnection in four stages of preliminary design, construction drawing design, construction optimization and operation maintenance. The study shows that the BIM platform can effectively promote the information exchange, improve the visualization of engineering elements, ensure the effective transmission of information, and provide the reference value for realizing the efficient collaborative management of information in the full life cycle of transportation infrastructure based on BIM technology.
