Effectiveness of Buttress and Cross-Wall in Deep Excavations
Buttress and cross-wall have been widely adopted with success in soft ground excavation work. The interaction between the soil, buttress/cross-wall and diaphragm wall is a three dimensional (3D) problem but in practice the problem is commonly simplified into a two-dimensional problem. This study compared the contribution of buttress and cross-wall on the displacement of diaphragm wall via a series of 3D finite element (FE) analysis. The numerical procedure was first calibrated against the field data obtained from a 16 m deep excavation project in Taipei City. The model was then used in the subsequent parametric study to evaluate the efficiency of buttress and cross-wall for a diaphragm wall supported excavation. Result showed that cross-wall and buttress were equally efficient in restraining the lateral displacement of diaphragm wall.
