AbstractIn this paper, the displacement performance of deep excavations supported by contiguous bored pile walls (CPWs) in soft clay is studied by analyzing the excavation case for a new main building for the Shanghai Civil Aviation Hospital. The relationships between the maximum displacements of CPWs, the maximum ground settlements, and excavation depth are analyzed, and compared with the statistical values presented in the literature. Empirical expressions are presented to predict the lateral deflection profile of CPWs, distribution curve of ground settlements, horizontal displacement in subsoil, and settlements of adjacent buildings. The parameters in these empirical expressions are obtained based on field measurements. A simple method is developed to predict the displacement performance of the deep excavations with CPWs, proving an approach to assess the deep excavations and leading to an optimized design and construction.
