Back analysis on deep excavations

Đang chuẩn bị nút TẢI XUỐNG, xin hãy chờ

Back analysis is necessary for further design and construction of deep basement projects in urban areas. This paper is to present two case studies that include 3 basements excavated up-to15m below current street level. Both Hardening Soil model (HSM) and Mohr Coulomb model (MCM) were applied for the analyses of geotechnical aspects. Inclinometers were installed to record diaphragm wall’s deflections before construction. |
