The researchers studied how different stress paths and consolidation stress ratios affect pore water pressure in saturated intact loess. They conducted tests on the loess under various conditions and found that positive pore water pressure increases with axial strain. Stress path changes greatly impact pore water pressure, especially under K0 consolidation. Consolidation stress ratio also influences pore water pressure characteristics, depending on the stress path. The formula for pore water pressure depends on changes in consolidation stress ratio and stress path.
