摘　　要：对昔格达地层组成成分及物理力学性能进行了总结归纳,分析了该地层特点。并将昔格达地层与隧道施工结合进行分析,指出昔格达组地层在空间与物理力学特征之间具有离散性。由于不同地区昔格达组不尽相同,发现微粒成分和疏松的结构决定了地层特性。对昔格达组地质隧道施工要点和事故案例进行了总结,指出昔格达组地质隧道开挖工法建议选择为预留核心土法,同时在施工过程中应及时支护并做好防排水措施。研究成果对类似工程具有一定的指导作用。This paper summarizes the composition and physical and mechanical properties of the Xigeda formation and puts forward the characteristics of this formation.The analysis was carried out by combining the Xigeda Formation with tunnel construction and pointed out that the Xigeda Formation strata have discrete types in terms of space and physical and mechanical characteristics.Since the Xigeda Formation differs in different areas,the particle composition and loose structure determine the formation characteristics.The construction key points and accident cases of the Xigeda Formation geological tunnel were summarized.It is pointed out that the excavation method of the Xigeda Formation geological tunnel is recommended to be the reserved core soil method.At the same time,timely support and waterproofing and drainage measures should be taken during the construction process.The research results have a certain guiding role for similar projects.
