SUBGRADE CONDITIONS REQUIRING SPECIAL DESIGNS

When unusual subgrade conditions are encountered during the design phase or the construction phase that need more focused attention, special designs are usually implemented. Such unusual conditions include, but are not limited to, soft and unstable subgrade conditions, unfavorable subgrade soil types, relatively high water tables, and anticipated drainage problems.

4.1 SOFT AND UNSTABLE SUBGRADE CONDITIONS

As described in Chapter 3 of this book, during the subsurface investigation phase of the project, most of the soft and unstable soil conditions can be identified. When these soft or unstable subgrade soil conditions are encountered, appropriate design details to account for these soil ...
