摘要
随着我国城市基础设施建设步伐的加快,在既有工程附近新建工程的情况逐渐成为普遍现象,而目前设计规范条文中相关的内容较少,甚至空白。以在既有隧道附近新建隧道为例,通过数值模拟分析,对新建隧道和既有隧道二者之间的相互影响进行了分析研究,为工程的设计、施工提供技术支撑。
With the quickening procedure of urban infrastructure construction in China, the newly built projects near the existing engineering gradually become a common phenomenon, but the relative contents are less, even blank in the current design code provisions. Taking a newly built tunnel near an existing tunnel as an example, the article analyzes and studies the interaction of the both newly built tunnel and the existing tunnel through the numerical simulation analysis, which can provide the technical support for the design and construction of the projects.
