A relatively economical and expedient numerical procedure and computer code based on the finite difference method were developed for predicting heave with time for heterogeneous expansive soils beneath structures idealized as two-dimensional. The computer code will also compute the potential heave assuming saturation of the foundation soils based on McDowell's swell data. The heave with time estimates should be useful for structures near which penetration of rainwater from the ground surface is permitted, provided that ponding of surface water and external water from leaking water and sewer lines does not occur. The potential heave should be useful if the foundation soils become saturated from excessive watering, poor surface drainage, and leaking water and sewer lines. The required input data include the structural load, specific gravity, liquid and plastic limits, initial dry density and water content, coefficient of vertical permeability, ratio of the horizontal to the vertical coefficient of permeability, and swell and suction relationships of the foundation soils.

Differential swelling and shrinkage of foundation soils are responsible for considerable damages to buildings and other structures in many parts of the world. One of these regions is in Jackson, Mississippi, and the surrounding area, where many types of structures have been damaged from movements of the underlying Yazoo clay formation. Field test sections, each containing an instrumented 100-ft-square area covered with an impermeable material simulating a lightweight structure, have been planned for five regions. The first test section was constructed near Jackson in October 1969 in an area underlain by the Yazoo clay formation. Results of field and laboratory investigations conducted prior to construction were used to estimate the amount of heave anticipated in the test area. The climate at Jackson is warm and humid. The test section was constructed on a moist soil profile. Negative pore water pressures of about 1 ton/sq ft have been measured in the laboratory in undisturbed samples of Yazoo clay. Accumulative heave of less than 0.04 ft measured during 1-1/4 years of observations shows a pattern of very slow change that may require years before the maximum heave is developed. (Author).

The problem of expansive clay soil with regard to structural damage of buildings and roads was not recognized until the latter part of 1930. Up to now, some engineers are not familiar with certain characteristics of this soil. Many clay soils may be mistaken for expansive ones and costly structural designs be prepared for structures to be founded on them. Therefore, there is a need to characterize the soil for ease of identification. In this regard, Dr. M'Ndegwa points out that expansive soil can be easily identified through local climate, vegetation, ground topography, physical features of soil and simple laboratory tests. This book defines expansive soil, its occurrence, formation, mineralogical and chemical structure. The author explains the swelling behaviour of clay soil and discusses factors that influence actual amount of swell or shrinkage, concepts of swelling, modes of swelling and mechanisms of swelling. The classification and identification of this soil type including its compaction characteristics are also described. Finally, evaluation of swelling potential is discussed. Students of Civil Engineering and Practising Engineers will find this book very resourceful.

Your guide to the design and construction of foundations on expansive soils Foundation Engineering for Expansive Soils fills a significant gap in the current literature by presenting coverage of the design and construction of foundations for expansive soils. Written by an expert author team with nearly 70 years of combined industry experience, this important new work is the only modern guide to the subject, describing proven methods for identifying and analyzing expansive soils and developing foundation designs appropriate for specific locations. Expansive soils are found worldwide and are the leading cause of damage to structural roads. The primary problem that arises with regard to expansive soils is that deformations are significantly greater than in non-expansive soils and the size and direction of the deformations are difficult to predict. Now, Foundation Engineering for Expansive Soils gives engineers and contractors coverage of this subject from a design perspective, rather than a theoretical one. Plus, they'll have access to case studies covering the design and construction of foundations on expansive salts from both commercial and residential projects. Provides a succinct introduction to the basics of expansive soils and their threats Includes information on both shallow and deep foundation design Profiles soil remediation techniques, backed-up with numerous case studies Covers the most commonly used laboratory tests and site investigation techniques used for establishing the physical properties of expansive soils If you're a practicing civil engineer, geotechnical engineer or contractor, geologist, structural engineer, or an upper-level undergraduate or graduate student of one of these disciplines, Foundation Engineering for Expansive Soils is a must-have addition to your library of resources.

Foundations on Expansive Soils provides the practicing engineer with a summary of the state-of-the-art of expansive soils and practical solutions based on the author's experience. The book is organized into two parts. Part I deals with theory and practice, and summarizes some of the theoretical physical properties of expansive soils. It also discusses various techniques employed to found structures on expansive soils such as drilled pier foundation, mat foundation, moisture control, soil replacement, and chemical stabilization. Topics covered include the origin, mineralogical composition, and the basic structure of expansive soils; the migration of water, swelling potential, and swelling pressure; site investigations and laboratory testing; moisture control; and soil stabilization. Part II presents case studies on the following: distress caused by pier uplift; distress caused by the improper design and construction of a drilled pier foundation system; distress caused by heaving of footing pad and floor slab; distress caused by heaving of continuous footings; and distress caused by a rise of ground water.
