| 摘 要： | SMW工法桩在当今地铁基坑中被大量使用,为了对该种基坑开挖引起建筑物沉降进行研究,针对天津市地铁二号线曹庄站施工中基坑的周边建筑物沉降进行现场监测,采用曲线拟合最小二乘法对基坑周边建筑物监测的数据进行研究,根据现场实测沉降值拟合出曲线方程,再按拟合出的曲线方程求出拟合值,将实测值与拟合值进行比较,其平均相对误差为4.1...

| Abstract: | Composite steel soil-cement mixed diaphragm walls are widely used in nowadays metro excavation.In order to investigate building settlement caused by this kind of excavation,we conducted an on-site inspection of building settle-ment around the pit in the construction of Caozhuang Station in Tianjin Metro Line 2 and analyzed the monitoring data ar-ound the building via least squares curve fitting.According to the measured sedimentation,we fitted the curve equation and then derived the fitted values.Comparing ... |
