摘要
文中以水平位移现场监测成果为基础,开展了数据分析,结果表明,基坑不同位置的水平位移值存在较大差异,但随时间推移,水平位移有持续增加的特征;同时,水平位移随深度亦有所变化,大致在13m处的水平位移值最大。在变形预测结果中,预测精度较高,验证了预测模型的有效性,且水平位移的累计变形后续仍会进一步增加,但增加速率趋于减小和稳定。
Based on the field monitoring results of horizontal displacement,the data analysis is carried out.The analysis results show that the horizontal displacement values at different locations of the foundation pit are quite different,but the horizontal displacement has the characteristics of continuous increase over time;At the same time,the horizontal displacement also varies with the depth,and the maximum horizontal displacement value is approximately at 13m.In the deformation prediction results,the prediction results have high prediction accuracy,which verifies the effectiveness of the prediction model.The cumulative deformation of horizontal displacement will continue to increase,but the increase rate tends to decrease,and the overall trend is stable.
