Liquefaction Assessment and Excess Pore Pressure Model for Homogeneous and Stratified Soil-Ash System by Energy Approach
(Springer Nature, 2024) Amit Kumar Ram; Supriya Mohanty
The bulk production of fly ash from the primary source requirement brings the attention of the geotechnical engineers for the recommendation of mass utilization in a different area of civil engineering. The application of waste materials is normally done in stratified form, and their performance must be examined in static as well as dynamic conditions. The behavior of the waste material under static condition has been done in considerable amounts; therefore, in the present study, the shear modulus assessment of the homogeneous and stratified soil-ash deposits has been carried out. In addition, the strain energy per unit volume required for the liquefaction has also been investigated for the present combinations. The stratified soil shows higher shear modulus than that of the fly ash and local soil for shear strain of 0.3% and 0.6% and beyond 0.6%; it shows a comparable shear modulus as compared to the homogeneous one. The shear modulus versus shear strain variation of the present materials was comparable with the sand having higher fine content (or categorized as SP). The energy required for liquefaction is dependent on all the considered parameters, whereas it is independent of the cycle needed to liquefy. In addition to that, the excess pore pressure model has been developed for the homogeneous and stratified soil-ash deposit using a strain energy ratio as an independent parameter. © King Fahd University of Petroleum & Minerals 2023.
