Abstract

Simi-empirical equations for predicting lateral pile movement due to adjacent braced excavation in Bangkok subsoil are developed in this paper. The equations are derived from multiple-linear regression analysis of the artificial data, which are the relation between lateral pile deflection and influenced parameters. These data are generated from a large number of finite element (FE) analyzes of pile adjacent to deep excavation using the reasonable soil models and parameters of Bangkok subsoil condition. The soil model in the analyses is specially paid attention to soil stiffness at small strain range. The results of prediction of maximum pile deflection by developed equations are in good agreement with FE analysis data. However, this study deals with only one soil profile, more data with varying soil properties are necessary in further study for more general equations.
