摘要
根据上海地区某开挖深度16.15~16.75m,面积约25 500m2深大基坑实例的开挖监测数据,分析在上海典型深厚软土地层条件下,基坑的相关性状。分析表明相对常规3道支撑基坑,本基坑围护墙侧向位移要更大;根据本基坑施工工况结合监测数据分析,得出不同工况下侧向位移时间效应敏感性各有特点;最后分析了立柱竖向位移在不同工况下的表现,本文研究结论以期为类似工程提供借鉴与参考。
According to the excavation monitoring data of a 16. 15 ~ 16. 75 m meter deep and 25 500 m2 of deep foundation pit in Shanghai,to analyze the correlation of foundation pit under the condition of typical deep soft soil layer in Shanghai.Analysis shows that the lateral displacement of the retaining wall of the foundation pit is larger than that of the conventional three-course support pit. According to the construction situation of the foundation pit,combining with monitoring data analysis,it is concluded that the time effect sensitivity of lateral displacement under different conditions has its own characteristics. Finally,the vertical displacement of column under different working conditions is analyzed. The conclusions of this paper are expected to provide reference and reference for similar projects.
