Swelling Characteristics of Compacted, Expansive Soils
Abstraet-The limitations of existing methods for the prediction of swelling behavior of compacted softs are examined. Both the purely theoretical approach and the purely empirical approach are found to be inadequate. The present study is based on a semi-empirical approach in which a model of swelling behavior is developed leading to equations relating swelling potential or swelling pressure of ...
متن کاملSwelling pattern of polypropylene fiber reinforced expansive soils
Expansive soils are considered to be the one of the highly problematic soil. These soils undergo large volume change based on the amount of moisture content.. Because of this behaviour, lightly loaded civil engineering structures founded on the expansive soils gets severely damaged. There are several mitigating techniques available to counteract the problems posed by the expansive soils. In rec...
متن کاملNumerical Solution for Heave of Expansive Soils
A numerical solution for heave prediction is developed within the context theories for both saturated and unsaturated soil behaviors. Basically, lowering the potential level of compressing on a saturated layer will cause heaving due to water absorption. This water absorption is in an opposite way, similar to water dissipation as what happens during unloading in consolidation process. However, i...
متن کاملModelling plasticity of unsaturated soils in a thermodynamically consistent framework
Constitutive equations of unsaturated soils are often derived in a thermodynamically consistent framework through the use a unique ’effective’ interstitial pressure. This later is naturally chosen as the space averaged interstitial pressure. However, experimental observations have revealed that two stress state variables were needed to describe the stressstrain-strength behaviour of unsaturated...
متن کاملSwelling Clay Mapping For Characterizing Expansive Soils; Results From Laboratory Spectroscopy and Hysens Dais Analysis
Data acquired from the hyperspectral airborne sensor DAIS-7915 over Antequera in southern Spain was processed to yield a quantitative soil swelling potential map based on three physicochemical soil properties currently used in engineering as measures of soil swelling namely cation exchange capacity (CEC), coefficient of linear extensibility (COLE), and Saturated moisture content (SP). The metho...
