摘要
小曲线半径地铁盾构隧道施工难度大,尤其是位于填海区深厚淤泥和填石层时,其安全控制更是工程界亟待解决的难题。文章依托深圳地铁13号线工程,详细介绍填海区地层中修建小曲线地铁盾构隧道的设计施工关键技术,包括改造盾构机、定位加固地层、处理锚索和采用小幅宽管片等措施,相关经验可为其他类似工程提供参考和借鉴。
Constructing shield tunnel in small radius is not an easy task, especially in deep muck and rockfill region, so its safety control is of great importance in the industry. Based on the line 13 of Shenzhen metro,this paper introduces the key technology of design and construction for a small radius tunnel in reclamation area in detail, which are reconstructing shield machine,accurately consolidating foundation, handling anchor cable and using small breadth segment. This relevant experience can provide reference for other similar projects.
