地铁隧道穿越地裂缝处施工技术探讨

Probe into Subway Tunnel Construction Technology at the Place of Crossing the Ground Fissure

地裂缝地质灾害是地下隧道工程建设的重大难题之一,地裂缝附近洞体结构的科学处置是地铁隧道线路长期稳定正常使用的关键。通过对西安地裂缝特征的概述,分析了地铁隧道施工穿越地裂缝处时受到的不良影响,探讨了具体的施工技术。

The geological disaster caused by ground fissure is one of the important hurdles in the construction of tunnel engineering, and the scientific treatment of the cave structure near the ground fissure is the key for the long-term, stable and normal use of subway tunnel line. Through the overview of the features of Xi＇ an＇ s ground fissure, this paper analyzes some harmful effect on the construction of subway tunnel at the place of crossing the ground fissure, and probes into some concrete construction technologies.
