浅埋暗挖隧道下穿既有重载铁路安全技术研究

Safety Technique Research on Shallow Excavation Tunnel Beneath the Existing Heavy Duty Railway

山区重载铁路在地形受限、地质条件复杂等不利条件下实施铁路平交道口改立交工程,浅埋暗挖隧道不失为一种可行的方式。本文就石太线下安道口改立交工程的实践,着重阐述山区重载铁路复杂条件下实施浅埋暗挖隧道,确保行车和施工安全所采取的方法及技术措施,对其他类似工程具有一定的借鉴和指导意义。

Shallow tunnel excavation is a feasible way for heavy duty railway construction in mountain area with limited topography and complex geological conditions. Taking the Xia An level of Shijiazhuang-Taiyuan railway project as a case,the shallow tunnel excavation method in mountain area is clarified in this article.Several measures are proposed to ensure traffic safety and construction safety. It has certain reference and guiding significance for other similar projects.
