Session 01: Case Histories of Unexpected Behavior and Failure of Shallow, Deep and Other Foundations
Location

Abstract
Mexico has a considerable number of regions covered by expansive soils (12% of the total country area). One of these regions, named as “Cienega de Chapala”, is located in the state of Jalisco; the morphology of this region is mostly volcanic where plains and basins are found among volcanic formations. Plains and basins contain a variety of rocks mixed with volcanic ashes. The soil is formed by alluvial and lacustrine lands arranged in layers where the expansivity of superficial layers range from medium to high. This work describes two cases to illustrate typical problems originated by subsoil displacements. These displacements are produced by changes in soil humidity conditions that generate volumetric changes in such expansive soils. Both cases are educational facilities (i.e., college buildings) that have been seriously damaged by subsoil volumetric changes. This document also describes the soil characteristics, the buildings state before any rehabilitation work, the analysis performed, the obtained results, the solutions proposed, and the first findings about the buildings state after the rehabilitation works.

Foundations on Expansive Soils in Mexico
Arlington, Virginia
Mexico has a considerable number of regions covered by expansive soils (12% of the total country area).

Plains and basins contain a variety of rocks mixed with volcanic ashes. The soil is formed by alluvial and lacustrine lands arranged in layers where the expansivity of superficial layers range from medium to high. This work describes two cases to illustrate typical problems originated by subsoil displacements. These displacements are produced by changes in soil humidity conditions that generate volumetric changes in such expansive soils.
