Analysis of Time Series Changes of Deep Horizontal Displacement in Deep Excavation
To grasp the variation law of horizontal displacement in foundation pits,this article is based on the monitoring results of deep hori-zontal displacement in foundation pits,and carries out the current deformation law and prediction analysis.The analysis results show that there are significant differences in the maximum horizontal displacement values at different positions of the foundation pit,with a range of 12.85-29.52 mm and an average of 21.31 mm,both of which are less than the designed deformation control value of 35 mm,meeting the design re-quirements;As the excavation of the foundation pit continues,its horizontal displacement exhibits a continuous increase feature,and the hori-zontal displacement first increases and then decreases with increasing depth,with the maximum value mainly located between12.5~13.5 m.Meanwhile,through deformation prediction,the horizontal displacement of the foundation pit shows a convergent increasing trend,and the max-imum predicted value is also smaller than the deformation control value,indicating that under the prediction conditions,the horizontal displace-ment of the foundation pit still meets the requirements.
