摘要
为满足青岛地区硬岩及复合地层盾构掘进安全、快速的要求,盾构刀盘设计应符合工程地质要求。文中基于青岛地铁4号线某区间右线盾构施工段进行盾构针对性设计,结合盾构掘进参数分析盾构刀盘与区间地层的适应性,得出了盾构刀盘在硬岩及复合地层掘进参数的差异。分析表明,区间所选用盾构刀盘与该区间复合地层具有更好的适应性。
To meet the safety and speed requirements of shield tunneling in hard rock and composite strata in Qingdao area,the design of shield cutter head should meet the requirements of engineering geology.Based on the shield tunneling design of the right line shield tunneling section of a certain section of Qingdao Metro Line 4,the adaptability of the shield cutterhead and the strata in this interval were analyzed with the shield tunneling parameters.The difference in tunneling parameters of the shield cutterhead in hard rock and composite formations is obtained.The analysis shows that the shield cutterhead selected in this section has better adaptability to the composite stratum in this section.
