Prediction of Ground Movements and Impacts on Adjacent Buildings Due to Inclined–Vertical Framed Retaining Wall-Retained Excavations

Abstract

Inclined–vertical framed retaining walls were recently developed and successfully adopted in engineering practice. However, relevant empirical methods for the evaluation of ground movements due to excavation have not been established. This study aimed to establish a calculation method for assessing ground movement due to excavation and to evaluate the damage probability of nearby buildings. A series of numerical models were carried out, and a database was established with their results. In this paper, simplified equations are proposed for predicting the profiles of subsurface and surface settlements, as well as lateral movements, utilizing the database. The accuracy of the simplified equations was validated by monitoring data from three case histories of the inclined–vertical framed retaining wall. Finally, the damage potential index was used to obtain the probability of damage to buildings located outside the excavations, while considering different positions.
