摘要
结合某铁路隧道施工实例,对隧道流沙产生的原因及坍塌形态进行了详细的分析,制定了合理有效的施工措施,对其施工要点作了归纳,通过采取超前支护、尽早衬砌、封闭成环等措施,保证了隧道的安全、顺利施工。
By combining with the tunnel construction examples along some railway, the paper analyzes reasons for the shifting sand in tunnels and the collapse forms, makes some reasonable and effective construction roeasures, sums up some construction points, and guarantees the safety and the smoothness of the construction by adopting some measures, including advanced support, the early lining, the sealing ring closure.
