摘要
结合某地铁站深基坑施工,对基坑工程设计中常用的基本参数进行了对比研究.通过对各参数实测数据的曲线拟合和数值计算得出软土地区深基坑开挖对地表沉降的主要影响范围、沉降最大值及支护主体的最大水平位移,并把实测数据的数值计算结果与经验估算值进行比较,验证经验参数对同类软土地区的实际工程适用性,对地表沉降规律提出了分段分析的方法.
Referring to the deep foundation construction of a subway station, the comparative research on the basic parameters of the foundation engineering design is carried out. The main affected area of the ground surface subsidence, the maximum value of surface settlement and the largest horizontal displacement of the main support about deep foundation pit excavation in soft soil areas were obtained by the curve fitting and numerical calculation of the measured parameters data. Comparing the numerical calculation results of measured data with the estimate value of experience, this paper proves the fitness of the existing empirical parameters in similar soft areas, and offers advice on different methods on the analysis of each section to ground surface settlement.
