Analysis & Design of Deep Foundations Time: 10:30am to 12:30pm
This seminar/presentation will cover the salient features of the analysis and design of deep foundations. All structures need to have suitable foundation in or to stand. Since all the loads of the structures are finally transmitted to the foundation; there design must be judiciously made. The presentation consists of the brief introduction of deep foundations. A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. Deep foundation is required to carry loads from a structure through weak compressible soils or fills on to stronger and less compressible soils or rocks at depth, or for functional reasons. Deep foundations are founded too deeply below the finished ground surface for their base bearing capacity to be affected by surface conditions, this is usually at depths >3 m below finished ground level. Deep foundation can be used to transfer the loading to a deeper, more competent strata at depth if unsuitable soils are present near the surface. The various types of deep foundations in general use are hollow box foundations, caissons, cylinders, shaft foundations and pile foundations. Sample calculations will be presented of design of deep foundation of various types of soil conditions. This presentation will also include practical aspects (thumb rule) of design of deep foundation. Few illustrations of foundation failures will be done on account of poor design of deep foundation. Apart from that, discussion will be made on Types of Deep foundation and their suitability to various types of soil.
The main topics/highlights of this presentation are:
- Brief introduction of deep foundations.
