某地铁车站基坑监测结果分析

Monitoring and analysis of a metro station excavation

对坑内外土体严重扰动过后的某地铁明挖车站基坑进行了跟踪监测,主要分析了基坑围护桩深层水平位移及冠梁顶水平位移、支撑应力、支撑挠曲等监测数据,讨论了在现场条件较为复杂的情况下有效监测水平位移的方法,并给出了有益的结论和建议,以供参考借鉴。

This paper tracking monitored the foundation pit of a subway open excavation station after severely disturbing of inside and outside soil, mainly analyzed the deep horizontal displacement of foundation pit support pile, crown beam top horizontal displacement, support stress, support deflection and other monitoring data, discussed the method effectively monitored horizontal displacement under more complex situation, and gave some useful conclusions and recommendations, for reference.
