Aiming at the limitations of the traditional geodetic method in monitoring the deformation of the retaining piles in deep foundation pits,a stress-equivalent geometric deformation monitoring method based on inverse finite elements is pro-posed.The inverse finite element algorithm is used to establish the correlation model,and the geometric deformation of the re-taining piles under the pressure of the soil is equivalently solved,and the model is verified by simulation and examples.The ex-perimental results show that under different working conditions,the inverse finite element relationship model can realize the equivalent conversion of pile displacement,and has good accuracy and robustness.This method makes up for the deficiencies of traditional monitoring methods in internal monitoring of structures,provides a new idea for deformation monitoring of under-ground spaces such as retaining piles around deep foundation pits,and plays a positive role in promoting the automation of mo-nitoring work and scientifically predicting deformation.
