摘要
隧道施工严格按照"管超前、严注浆、短进尺、强支护、早封闭、勤量测"的18字原则组织施工。为确保工期,红土地站下穿段采用机械开挖结合控制(弱)爆破施工,施工影响范围内标准断面设计为双侧壁导坑法施工,采用机械开挖结合控制爆破(松动弱爆破)方式开挖。论述了工程概况、施工要求及相关施工工艺与方法。
Tunnel constructions should strictly follow the principles of Setting Steel Pipes At First, Strict Grouting, Strict Blast-hole Drilling, Strong Support, Early Closing and Frequent Measurement. To ensure the construction schedule, a subway station passing through red earth used a method combining excavating earthwork with machine and controlled blasting （for loosening rock）. This paper introduces project overview, construction requirements and relative construction proc- esses and techniques.
