摘要
分析了坑周超载大小、埋深等因素对地表沉降的影响。论述了坑周土体水平位移与地表沉降的关系,进而通过有限元分析得出超载作用下坑周附加地表沉降的线性分布规律,并结合上海地铁2号线河南中路站实测数据给出了超载影响系数K及考虑超载的坑周地表沉降表达式。
After analyzing the effect of magnitude and depth of adjacent overload on ground settlement and discussing the relationship between horizontal displacement and ground settlement around deep excavation, the paper concludes the linear distribution pattern of surrounding ground settlement under overload by FEM analysis. The overload influence coefficient K and the expression of surrounding ground settlement of deep excavations are attained according to the measured data of Henan Road Station of Shanghai Metro Line No. 2.
