摘要
结合工程概况,针对隧道断面大、工期紧、所处地质情况复杂的工程特点,简单介绍了其施工方法及支护措施,并对双侧壁导坑法、CRD与CD工法、三台阶临时仰拱法、全断面法等主要工法的施工工艺进行了阐述,从而确保安全快速掘进。
Combined with practical engineering,the author introduces the working method and supporting measure of the tunnel in light of its engineering characteristics as heavy section,tight time schedule,and complicated geological conditions,and illustrates the construction technology of main construction methods as double lateral wall heading method,CRD and CD working method,threestep temporary inverted arch method,and gross section method,in order to ensure safe and fast tunneling.
