Lessons Learned in Design of an Excavation with the Installation of Buttress Walls
並列摘要
Installation of buttress walls is one of the auxiliary measures for the protection of adjacent buildings during excavation in Taiwan. But only a few complete case studies with buttress walls have been found in the literature. This study performs a case study regarding the design of an excavation with the installation of buttress walls. Before excavation, a preliminary prediction concerning the diaphragm wall deflection was implemented using an empirical method and the three-dimensional finite element method. Based on the preliminary prediction, the buttress walls were designed. Then the diaphragm wall deflections were predicted again and the efficiency of the buttress walls was evaluated. During excavation, the prediction was modified following the actual field observation. Based on the results of the observation and prediction, a numerical analysis model was established and the efficiency of the buttress walls was investigated.
