Foundation In Expansive Soils

 

Course Summary

This course presents guidance and information for the geotechnical investigation necessary for the selection and design of foundations for heavy and light buildings constructed in expansive clay soil areas. The information in this course is generally applicable to many types of structures such as residences, warehouses, and multistory buildings. Emphasis is given to the maintenance of an environment that encourages constant moisture conditions in the foundation soils during and following construction. Special attention must always be given to specific requirements of the structure such as limitations on allowable differential movement.

Learning Objectives

Guidelines of the geotechnical investigation and analysis necessary for selection and design of buildings constructed in expansive clay soil areas, as outlined in chapters 2 to 5, consist of methods for the recognition of the relative magnitude of the swelling soil problem at the construction site, field exploration, laboratory investigations, and application of methodology for prediction of volume changes in swelling foundation soils. Chapter 6 presents guidance for selection of the type of foundation with structural details of design procedures provided for reference. Chapters 7 to 9 discuss methods of minimizing foundation movement, construction techniques and inspection, and considerations for remedial repair of damaged structures.
