ANALYSIS OF BASE HEAVE IN DEEP EXCAVATIONS

The paper reviews traditional methods for both checking the stability of excavations and estimating ground movements as soil is removed. These methods do not allow for the effects of wall stiffness, embedment depth or end fixity. A finite difference technique is described which can be used to model realistically an excavation system and hence to evaluate factor of safety as well as estimated base heave and associated ground movements. Three cases are analysed and the results presented and compared with those obtained using traditional methods. (Author/TRRL)
