SETTLEMENT DUE TO DIAPHRAGM WALL CONSTRUCTION IN RECLAIMED LAND IN HONG KONG

For more than 2 decades, diaphragm walling has been commonly used in the construction of deep excavations in Hong Kong. Diaphragm walls were particularly appropriate to the Mass Transit Railway construction in over-crowded urban Hong Kong, limiting adverse effects on surrounding buildings and allowing top-down construction methods, thus reducing programming time. Settlement was predicted for structures on deep pile foundations, adjacent to deep excavations, and the actual settlement was monitored by conventional surveying techniques. Results show that settlement due to diaphragm walling is generally substantial and that preconstruction activities such as ground treatment, drilling, and preboring for wall panels, must be taken into account in any settlement predictions.
