Probabilistic method for displacement back analysis of deep excavations in soft soil based on Bayesian method
“In the field of deep excavation engineering, experts have proposed a soil parameter inversion method based on Bayesian parameter update framework and on-site monitoring data. An implicit function relationship between soil parameters and the lateral displacement of the retaining wall is established through GA-BP neural network. A Bayesian inverse analysis model is established based on monitoring data to verify the feasibility of the method, providing a solution for optimizing excavation support schemes and reducing engineering risks.”
