摘　　要：为揭示东北地区地铁车站深基坑沉降变形特性,以沈阳地铁下深沟车站深基坑工程为依托,采用理论分析和现场观测的方法,推导了适合沈阳地区深基坑的最大下沉点位置和最大下沉量的计算中关键参数地基土最大下沉角的公式及值,并得到基坑外地表沉降变形最大点位置和沉降量公式.研究结果表明,地基土最大下沉角的合理性和理论计算方法的可行性.研究结论初步突破了传统沉降变形预测的计算方法,有助于寻求沈阳乃至东北地区的地铁车站深基坑设计施工中沉降变形分析和预测的有效途径.To reveal the characteristics of the deep excavation of metro station settlement deformation in northeast China,this paper took the Shenyang subway station deep foundation pit engineering as the base,and by using theoretical analysis and field observation method,derived the maximum subsidence position and the maximum amount of subsidence calculations for deep foundation pit of Shenyang key parameters：the maximum angle of soil subsidence formulas and values,and obtained the maximum settlement deformation excavation field table position and settlement formula.The results show the rationality and feasibility of the theoretical calculation method of the maximum angle of soil subsidence.Preliminary findings of the preliminary calculation method to break the traditional settlement deformation prediction,help to find effective ways to Shenyang and Northeast regions of the subway station deep foundation design and construction of settlement deformation analysis and prediction.
