Design Methods for Shallow Foundations
For sites where the heave is predicted to be of sufficiently small magnitude, shallow foundation systems such as conventional footings or stiffened slabs‐on‐grade may sometimes be used. This chapter discusses design and application of spread footings and stiffened slabs‐on‐grade. It also discusses differential heave beneath slabs‐on‐grade. Design of stiffened slab foundations on expansive soils is based on modeling the interaction of the soil with the slab subjected to the loads imposed by the structure. Probably the most commonly used remediation plan for shallow foundations that have experienced distress due to heave of expansive soils is to underpin the foundation. Various methods of underpinning can be used depending on the soil and foundation conditions. The chapter presents a case study, which demonstrates the use of an economical and innovative geophysical method to determine the length of existing push piers and helical piles.
