摘　　要：城际铁路因建设于市区,各工点施工场地大多受限。区间隧道具有断面大、距离长、埋深大、工期紧迫、地质复杂等特点,针对大长区间,一般在区间分段设置工作井。文章通过研究φ9100 mm级别盾构机尺寸及施工作业的空间需求,分析了盾构工作井尺寸,旨在为类似工程的勘察设计工作提供参考。Because the construction of intercity railway is in urban areas,the construction sites are mostly restricted.The interval tunnel has the characteristics of large section,long distance,large buried depth,urgent construction period and complex geology.For the large and long interval,the working well is generally set up in the interval section.By studying the size ofφ9100 mm shield machine and the space requirements of construction operation,this paper analyzes the size of shield working well,so as to provide reference for the investigation and design of similar engineering.
