摘要
对某工程深基坑围护结构水平位移变形监测资料进行分析,验证了最大变形所在位置基本符合工程经验。采用有限元软件拟合了实际监测数值并模拟在不同厚度下墙体变形情况,发现曲线呈现类似正态分布密度函数曲线。不同厚度对围护结构最大侧移影响的显著曲线大致可以用双曲线y=k/x来拟合,可以结合设计围护结构厚度,预估最大侧移值。
The analysis of horizontal displacement monitoring data on deep foundation excavation retaining structure of Changfujie metro station shows that the position of the maximum horizontal displacement was accordance with experience. Imitating the actual monitoring data and simulating kinds of displacement with a finite element software in different thickness of diaphragm wall, the authors discovered the simulation curves was familiar to the curves of normal distribution density function. Correlation was observed between the maximum horizontal displacement and the different thickness of diaphragm wall as a hyperbola y = k/x, the future maximum displacement could be calculated according to the design thickness of diaphragm wall.
