摘要
结合郑西铁路客运专线潼洛川、高桥、凤凰岭3座大断面湿陷性黄土隧道的施工,分析并总结出地表沉降开裂、拱顶下沉、水平收敛与开挖工序、雨水的关系和变形规律,由此提出大断面湿陷性黄土隧道施工变形控制的措施,并提出控制变形需进一步研究探讨的设计与施工建议。
Based on the construction of three large-section collapsible, Tongluochuan Tunnel, Gaoqiao Tunnel and Fenghuangling Tunnel, this paper analyzes and summarizes the deformation rules and the relationship between ground crack, vault settlement, horizontal shrink and excavation process, loess water. In the light of construction experiences and lessons, the deformation-controlling measures for the construction of large-section collapsible loess tunnels are concluded. Some problems about design and construction technology are also submitted to be further probed and researched.
