摘要:
结合兰渝铁路大断面软岩隧道两水隧道施工这一工程实例,就横洞和大跨软岩隧道交叉口施工方案进行比选,并对主洞与横洞交接处的加强措施和2种进洞方法各自施工方法的转化、施工技术措施等进行阐述,通过工程实例验证得出采用“方案一”比较适合于软岩隧道横洞进主洞。
关键词: 两水隧道, 软岩隧道, 横洞进主洞, 小导洞, 方案比选
Abstract:
Regarding the construction of the connection section between the horizontal adit and the main tube of Liangshui tunnel on LanzhouChongqing railway, two construction schemes are presented and analyzed in the paper. In the end, the first scheme is adopted. The technical measures taken in the construction are described. The construction practice demonstrates that the construction scheme adopted is suitable for the construction of the connection section between the horizontal adit and the main tunnel in soft ground.
Key words: Liangshui tunnel, tunnel in soft ground, connection section between horizontal adit and main tunnel, pilot tunnel, construction scheme selection
