AbstractThe demerits of level surveys for assessing foundation movements associated with moisture-induced volume change of soils have been well discussed and debated in the literature. In spite of the limitations of level surveys, and the associated strong desirability of benchmarked survey data for assessment of foundations movements on moisture sensitive soils, unbenchmarked level surveys continue to be used in forensic studies of buildings damaged by expansive and collapsible soils. The commo...

AbstractThe efficacy of removal and replacement as a mitigation alternative for expansive soil is discussed in view of numerical unsaturated flow/deformation results. Observations with respect to selection of depth and replacement soil type (similar, more, or less permeable than underlying expansive clay) are presented in the context of unsaturated flow and stress/deformation principles. Comparisons are made between various remove and replace options on the basis of extent and degree of wetting ...

In assessing the probable settlements of a heat generating structure on unsaturated soil three stress state variables that are of key importance are (a) temperature, (b) net normal stress, and (c) soil suction. Neglect of or substantial error in evaluation of any one of these three variables can result in substantial error in the estimation of thermally induced soil settlement. It is possible to obtain upper bound estimates of the thermally-induced strains by employing a low-cost laboratory test...

Methods of computation for soil heave based on an “equivalent” net normal stress path approach often have built-in assumptions regarding the relationship between in situ matric suction, overburden stress, and swell pressure. The term “matric suction equivalent” has been previously defined as the difference between in situ state of stress projected on the net normal stress plane (represented by swell pressure) and overburden stress. Correlations between matric suction, overburden stress, and swel...

Design of foundations for expansive and collapsible soils is an important challenge facing engineers. The state of the practice in this area has been changing over the past decades. The standard of care and definitions of the state of the practice and the state of the art are discussed, followed by an in-depth treatment of the state of the practice. The authors present what they consider to be the appropriate practice for field investigation techniques, laboratory testing, and foundation design ...

This paper investigates the shear strength and volume change of collapsible soils subjected to static and dynamic shear loading under a range of confining pressures and wetting conditions. The authors conduct tests on reconstituted samples simulating compacted engineered fill and natural density samples. Triaxial response-to-wetting tests are performed under soaked or backpressure saturated conditions before shear loading. An image processing technique is used to measure volumetric strains. A se...

This study examines the effects of apparatus compressibility and applied initial net normal stress on measured swell pressure for undisturbed specimens. Samples covering a wide range of properties were collected and consistency of trends in behavior for several “companion” sets of undisturbed specimens were examined. Failure to account for apparatus compressibility results in unintended swell of the specimen. This reduced the constant volume swell pressure by as much as half for the specimens. M...
