Top-down Excavation of a Metro Station in Soft Clay
This study examines the performance of a deep metro excavation constructed by top-down technique in Shanghai clay deposits. The monitoring items included deflections of diaphragm walls, vertical movements of steel columns, and axial forces of the struts. Based on analysis of the field measurements, some interesting findings were obtained, which will be useful for both practitioners and researchers.
