论文摘要
[摘要] 广州市轨道交通三号线梅花园站为3层岛式地下站,采用地下连续墙内支撑。该站周边场地狭窄、管线密集、基坑所处地质条件非常复杂。对地下连续墙侧向变形、支撑轴力、基坑外地下水位、土体深层位移和地面沉降等进行监测,并对监测得到的变形规律进行分析。监测结果表明:地下连续墙水平位移最大值较大,变形值受土体性质、天气(主要为降水)、开挖、加撑等影响显著,且地面超载对地面沉降影响不容忽视。

Monitoring  Analysis on Foundation Excavation Internally Supported with Diaphragm Wall in Complex Environment
 
Abstract:Internal support of diaphragm wall is used in Meihuayuan station of Guangzhou Subway No.3 Line, which is a three floors island station with limited surrounding site, dense pipelines and complicated geological conditions. Lateral deformation of diaphragm wall, axial forces of supports, underground water level outside foundation excavation, deep soil displacement and ground subsidence are monitored and corresponding deformation rule is analyzed. Monitoring r
esults show that the largest horizontal displacement of diaphragm wall is rather large, and its deformation is obviously influenced by soil properties, weather mainly including rain water, excavation and support. Furthermore, ground settlement is significantly influenced by overload on ground surface.
Key words:subway; deep foundation excavation; diaphragm wall; lateral deformation; deep displacement of soil; ground settlement
