深厚软土地层中深基坑支护结构变形分析与应对措施

Deformation Analysis and Countermeasures of Deep Excavations Pit Support Structure in Deep Soft Ground

以某深基坑在深厚软土地层条件下支护结构的变形为背景,结合理论计算与现场实测数据,对软土地区基坑支护结构的变形情况进行分析对比,提出深厚软土地层下支护结构设计及施工方面的注意事项,同时将分析结果应用于其他类似工程,减少深厚软土地区深基坑开挖风险,为后续类似工程积累经验。

As the background of analyzing the displacement of the protection structure based on monitoring data under deep mollisol conditions in subway station,combined with the theoretical calculation and field measured data,also analysised and contrasted the displacement of protection structure,proposed designing and construction matters that need attention,applied the results of analysis to the other similar projects at the same time,reduce the risk of station under deep mollisol conditions,accumulate experience for subsequent similar projects.
