The invention relates to the technical field of deformation prediction, in particular to a lateral deformation
prediction system and method based on a deep foundation pit wall body, and the
system comprises a deformation data collection module which collects a ground surface settlement monitoring value and a
lateral displacement monitoring value of a corresponding measuring point of the deep foundation pit wall body, carries out the
time sequence alignment
processing of data points, removes an abnormal monitoring value, and obtains a deformation data collection module; and establishing calibration deformation sequence data. According to the invention, through real-time acquisition and strict execution of data
time sequence alignment
processing, the consistency of ground surface settlement data and wall
lateral displacement data is ensured, abnormal
monitoring data is effectively eliminated, and the
data accuracy and consistency are improved; in the spatial interpolation process, width measurement of a settlement area is introduced, the width characteristic of a settlement groove is determined, and the
earth surface deformation trend is captured according to a deformation index; and extracting the maximum
lateral displacement of each time section of the monitoring section, establishing a dynamic corresponding relation between the
maximum displacement and the width of the
settling tank, and identifying the regular influence of the change of the construction process on the lateral deformation.
