Abstract:

The main objectives of this book are to present some of the available techniques for estimating the settlement of shallow foundations on cohesionless soils, and to compare predicted and observed structure settlements. The techniques for estimating settlements that are addressed include: methods based on penetration tests; methods based on pressuremeter tests; and methods based on elastic theory using compression moduli derived from pressuremeter tests, seismic wave velocities, and the Hardin and Black equation. These are representative of the techniques available to the geotechnical engineer, although they are not the only ones. Each of the methods described has its advantages and disadvantages. The simpler techniques, such as methods based on penetration tests, are inexpensive to apply but are very approximate. The more complex techniques allow the engineer to make a better estimate of the compressibility of the soil and to account for changes in compressibility due to stress changes caused by excavation, backfill, and structure loads; their disadvantage is that they require more detailed (and therefore more expensive) subsurface investigations and analysis. The geotechnical engineer has to balance these considerations in selecting the method or methods to be used on a particular project.
