Abstract:Aiming at the problems of large deformation calculation errors and low accuracy in numerical analysis methods for foundation pit engineering,a geological parameter inversion analysis method based on GWO-SVR is proposed in combination with existing monitoring data,which can achieve more accurate deformation calculation of foundation pits,especially suitable for foundation pits with significant deformation.On this basis,the causes of large deformation during the excavation process of adjacent anchor cable foundation pits are studied,and two different deformation control measures are compared and calculated.The effectiveness of the treatment measures is analyzed through measured data.The selection of the spacing between anchor cable foundation pits has a significant impact on the stability of the foundation pit and the stress of the supporting structure.By using numerical analysis methods,the deformation and internal forces of the foundation pit support piles,anchor cable forces,and soil pressure between piles under different spacing conditions are proposed.This can achieve differentiated design of the supporting structure for anchor cable foundation pits under different spacing conditions,providing reference for the selection and calculation analysis of anchor cable foundation pits.
