Dynamics of Soils and Their Engineering Applications
Author: Swami SaranPublisher: CRC Press
ISBN: 1000298353
Category : Technology & Engineering
Languages : en
Pages : 576
Book Description
The book offers systematic dynamic analysis of soils and their engineering applications, including machine foundations, and aims to develop a clear understanding of the subject. It comprises sixteen chapters. Chapter 1 introduces the reader to the various problems in soil dynamics. In Chapter 2, concepts of theory of vibrations are discussed along with their applications in designing Vibration Absorbers and Pickups. Wave propagation in elastic medium including wave refraction in layered medium is covered in Chapter 3. Chapter 4 deals with the procedure of determining dynamic properties of soils using various laboratory and field tests. Dynamic earth pressures in retaining walls and dynamic bearing capacity of footings are dealt with in Chapters 5 and 6 respectively. Chapters 7and 8 respectively deal with dynamic behavior of pile foundations and slopes. Causes of liquefaction of soils and prediction of liquefaction potential have been discussed in Chapter 9. In Chapter 10, the procedure of estimating the unbalanced forces in various types of machines are covered. Chapters 11, 12 and 13 deal with the analysis and design of foundations of reciprocating machine, hammer, and turbo-generators respectively. In Chapter 14, problems of vibration isolation and screening are dealt with. Chapter 15 discusses the analysis and design of reinforced earth wall located in seismic areas. A new concept of a conventional rigid retaining wall having reinforced backfill is presented in Chapter 16, giving complete analysis and design procedure considering seismic forces.
A Model Study of Dynamically Loaded Square Footings on Dry Sand

Book Description
The investigation reported herein was undertaken to develop an approach to modeling displacements of surface and shallow-buried footings on dry sand subject to high-intensity, single-pulse loads. A hypothetical shallow-bured structure with an isolated footing loaded by airblast overpressure produced by detonation of a nuclear weapon was assumed for design of load pulses on nine model footings used: footing widths of 4.5, 6.0, and 7.5 in. and depth-of-burial to footing width ratios of 0, 0.5, and 1.0. The principles of similitude were used to scale length, force, and time in the models. The models were placed in mobile test bins of uniform, fine, dry sand (90 percent relative density) and subjected to dynamic and static loading. Nondimensional load-displacement relations dependent only on depth-of-burial ratio were developed relating maximum displacement to peak dynamic load, footing width, and soil shear strength gradient. When the dynamic response of the footings in the form of reaction-displacement curves was compared with static response, an increase in initial stiffness and ultimate strength was observed for dynamic loading. However, these dynamic increases were greatest when the static shear strength was lowest, i.e. footings on the surface, and were least for footings buried at a depth equal to its width where the static overburden produced a substantial increase in shear strength.
