Based on the SPTs, it can be seen that the soil at depths ranging between 0–2.5 m has low blow counts. In addition, the soil at depths ranging between 0–5 m was confirmed to be silty sand based on laboratory experiments.
WebJan 31, 2024 · Blow count. In a standard penetration test (SPT), blow counts are used to determine the overall strength and density of soil. To measure the blow count, a weighted drive hammer will be dropped repeatedly onto the soil, counting the number of blows it takes to drive down per 6 inch increments.
