Influence of Tip Movements on Inclinometer Readings and Performance of Diaphragm Walls in Deep Excavations
Experience indicates significant movements at tips if inclinometers were not properly anchored in competent strata and, as a result, readings often indicated false outward wall movements in later stages of excavation. On the other hand, it has been observed that the changes in lengths of struts are minimal once these struts are preloaded; therefore walls can be assumed to be steady at corresponding strut levels in the subsequent excavation. Inclinometer readings can then be calibrated accordingly. Procedures have been proposed previously based on the experience learned from deep excavations carried out in the Taipei Basin. These procedures are substantiated herein by finite element analyses using the computer program PLAXIS.
