摘要
文章结合实地调研和模型实验,探讨盾构隧道在地裂缝影响下的变形控制技术.研究结果表明,随着地裂缝距离的变化,盾构隧道竖向变形可分为整体沉降、不均匀沉降和稳定三个阶段;在设计上应重视隧道顶部的抗拉性能,并采用高强度混凝土设计底部,以应对地裂缝对隧道结构的影响.这些研究成果对提升地铁隧道施工质量和地下空间利用具有重要参考价值.
Abstract
This paper Combined with field investigation and model experiment,the deformation control technology of shield tunnel under the influence of ground fissure is discussed.The results show that with the change of ground fissure distance,the vertical deformation of shield tunnel can be divided into three stages:overall settlement,uneven settlement and stabilization;attention should be paid to the tensile property of the tunnel top in the design,and high-strength concrete should be used to design the bottom to deal with the impact of ground fissure on the tunnel structure.These research results have important reference value for improving the construction quality of subway tunnels and the utilization of underground space.
