Description
Book SynopsisThis book gives both students and practising civil engineers an authoritative review of the state-of-the-art of designing deep foundations, excavations and tunnels. In addition, the case studies and numerical modelling presented will give valuable insights into the challenges of soil-structure engineering.
Table of ContentsPart 1: Deep foundations – piles, barrettes Uses and types of piles and pile groups Vertical pile load transfer mechanism Failure load on piles: definitions, interpretation and criteria Establishment of new failure load criterion for large-diameter bored piles and barrettes Analysis, design and parameters Dynamic formulae Design of rock-socketed piles Case studies: rock-socket piles Pile instrumentation: a case study of a well-instrumented barrette in Kowloon Bay, Hong Kong Case studies: 15 full-scale loading tests on barrettes in Hong Kong Case studies: bored piles in weathered materials Hong Kong Settlement analysis of piles and pile groups Summary Part 2:Multi-propped deep excavations Stress paths in relation to a deep excavation Plastic geo-structural analysis Preliminary design for deep excavations (short course notes) Instrumentation: a case study of a multi-propped excavation at Lion Yard, Cambridge Lateral pressure of wet concrete in diaphragm walls Stress transfer and deformation mechanisms around diaphragm walls Effects of modelling soil non-linearity and wall installation on back-analysis of deep excavations in stiff clay Comparison of Wall-Installation-Modelled (WIM) and Wished-In-Place (WIP) analyses with Mohr Coulomb model Prediction of ground movements due to diaphragm wall installation The prediction and control of displacements around deep excavations in Completely Decomposed Granite Summary Part 3: Bored and open face tunnelling below cities Unsupported tunnels: theoretical assessment of the collapse of soil arches Modern tunnel construction techniques Principal design and construction requirements Case study: the Heathrow Express Trial Tunnel Finite element modelling of multi-tunnel interactions and tunnelling effects on adjacent piles Effect of ground movements on buildings Case study: Effect of the Jubilee Line Extension on the Big Ben Clock Tower Summary
