摘要
上海大悦城二期项目开挖深23.1m,基坑西南侧4.5m有35kV变电站,为重点保护对象,该段采用48mCSM槽壁加固,以此项目为背景,对CSM施工时遇到的特殊地层中成墙效率低、垂直度偏差过大等问题及改进措施进行介绍,对以后在类似工程中的CSM施工提供了一定的参考价值。
Shanghai Joy city phaseⅡproject excavation,the depth of it is 23.1 m,foundation excavation southwest 4.5 m has a 35 kV transformer substations,as key protection object,the segment with 48 MCSM trench wall reinforcement.Taking this project as the background,the CSM special stratum are introduced.when the construction of the wall problem such as low efficiency,excessive verticality deviation and improvement measures For future similar projects in the CSM construction provides the certain reference value.
