Hydraulic Conductivity, Grain Size Distribution (GSD) and Cement Injectability Limits Predicted of Sandy Soils Using Vipulanandan Models
Abstract In this study, permeability, particle size distribution of the sandy soils and collected data from several research studies were analyzed and modeled using Vipulanandan p–q model and the results of prediction were compared with the Fredlund and Logistic Growth models used in the literature. The Vipulanandan p–q model was modified and used to represent the particle size distribution of soils. The Vipulanandan p–q model parameters were correlated very well to various soil properties such as the diameter in the particle size distribution curve corresponding to 10%, 30%, 60%, and 90% of finer ($ d_{10} $, $ d_{30} $, $ d_{60} $, and $ d_{90} $ respectively), mean particle size the diameter in the particle size distribution curve corresponding to 50% finer ($ d_{50} $), and fines content (F%). The range of particle sizes investigated in this study was 0.14–0.94 mm, 0.075–1.76 mm, and 0.15–3.59 mm for the $ d_{10} $, $ d_{30} $, and $ d_{60} $, respectively. Also, from the Vipulanandan p–q model parameter, the permeability of the soils have been predicted successfully. A current study also had quantified the lower groutability limit based on the $ d_{50} $ and the Vipulanandan p–q model parameters. The relationship between fines content and $ d_{50} $ were also generalized using the Vipulanandan p–q model to quantify the upper and lower groutability limits for sandy-soils.
