Laboratory test and mathematical model study on compaction characteristics of fully weathered granite in tunnels
Typical strata encountered in the project were selected as experimental soil samples,and lateral confined compression tests were conducted under conditions of 12%to 32%water content to obtain stress-strain curves for undisturbed soil consolidation under different water content conditions.With the help of the Origin data analysis software,a mathematical model was established using data fitting to describe the nonlinear compaction process of fully weathered granite,and the compression characteristics of fully weathered granite under conventional grouting pressure(0-4 MPa)were quantitatively studied.
