Witryna31 paź 2024 · As compared with dry soils, water plays more significant role, for load-bearing capability than the sand grains. The soil with lower clay/sand ratios has stiffened the mechanical properties under water saturated state, and pure clay and pure sand have reduced mechanical properties. 15.4 Conclusions WitrynaThe sands varied in grading and angularity, though at a strain rate of 103s−1the results for all three sands indicated a reduction in stiffness in 20% saturated samples compared to the dry sand, followed by a stiffening response for saturations of 40−100%, with the onset of lock-up behaviour varying between sands.
