Empirical correlations for the compression index of Irish soft soils
Numerous correlations have been developed in the literature relating the compression index Cc of soft soils to simple index properties that serve as a useful reality check on oedometer test results.… Expand
Pile groups under axial loading: an appraisal of simplified non-linear prediction models
The settlement behaviour of vertically loaded pile groups has been the subject of an extensive body of research over the past two decades. In particular, this work has identified the over-conservat...
An analytical approach for the prediction of single pile and pile group behaviour in clay
Abstract In this paper, the ‘ t – z method’ is employed to describe the nonlinear behaviour of a single pile and is used to obtain simplified predictions of pile group behaviour by considering the… Expand
Biaxial Loading of Offshore Monopiles: Numerical Modeling
AbstractIn this study, finite-element (FE) modeling was used to examine the influence of biaxial lateral loading of a monopile foundation. Two different soil models were adopted to investigate the… Expand
Experiences of utility microtunnelling in Irish limestone, mudstone and sandstone rock
Abstract There is currently no published guidance on the excavatability of Irish rock for microtunnelling applications. In this paper, new data and experiences of microtunnelling through rock (using… Expand
Numerical simulations of the reuse of piled raft foundations in clay
- Brian B. Sheil
- 6 February 2017
The development and growth of urban environments in recent years is requiring geotechnical engineers to consider foundation reuse as a more sustainable solution to inner city redevelopment. Two main… Expand
A practical approach for the consideration of single pile and pile group installation effects in clay: Numerical modelling
The first author gratefully acknowledges the College of Engineering and Informatics, NUI Galway, and the University of California Education Abroad Program for funding this research. In addition,… Expand
Interpretation of pipe-jacking and lubrication records for drives in silty soil
Abstract In recent years, there has been an increased resort to microtunnelling/pipe-jacking as a means of constructing underground conduits (for water, sewage, gas, and other utilities) to avoid… Expand
Instrumentation and Monitoring of a Concrete Jacking Pipe
Full-scale laboratory testing of a buried pipeline in sand subjected to cyclic axial displacements
This paper describes a full-scale laboratory study of the axial sliding behaviour of a trenched pipeline surrounded by sand backfill. Cyclic axial displacements are applied to a heavy pipe buried i...
