铁路黄土双线隧道由于其埋深浅、工程地质条件复杂,隧道施工时易出现地表开裂、大变形等施工灾害。该文结合陕西省西宝客运专线小村隧道工程实际,采用现场调查、理论分析和数值模拟等手段对小村隧道地表裂缝的形成原因进行了探讨,并针对该施工灾害的特点,提出了相应的治理措施和建议,可为类似工程的建设提供参考。
Because of its shallow depth and complex engineering geological conditions, railway loess double-track tunnels are prone to construction disasters such as surface cracking and deformation during tunnel construction. Based on the actual project of Xiaoetun tunnel in XiBao Passenger Dedicated Line in Shaanxi Province, this paper discusses the causes of the formation of surface cracks in XiaoCun tunnel by on-site investigation, theoretical analysis and numerical simulation. According to the characteristics of this disaster, Measures and suggestions can provide reference for the construction of similar projects.
