摘要
以无锡地铁4号线刘潭站北侧220kV高压线下围护形式设计为例,对设计方案进行比选,基坑采用钻孔灌注桩+止水帷幕的围护结构形式,满足高压线下施工净高要求。并对施工过程及监测情况进行分析、总结,并提出合理化建议,为后续地铁工程中类似项目情况提供借鉴。
Taking the enclosure form design of 220kV high voltage line under the the north side of Liutan Station of Wuxi Metro Line 4 as an example, the design scheme is compared and selected. The foundation pit adopts the form of enclosing structure of bored pile and waterproof curtainto meet the net high construction requirements under high-voltage line. Analyze and summare the construction process and monitoring situation, and put forward reasonable suggestions to provide reference for similar projects in the subsequent subway projects.
