oa Civil Engineering = Siviele Ingenieurswese - Penetration testing : test procedures and design use in South Africa



Penetration testing is used to gain both a qualitative and quantitative description of the ground to enable the design of geotechnical structures. The two penetration tests commonly used in southern Africa are the standard penetration test (SPT) and the dynamic probe super-heavy (DPSH) test. The SPT is carried out at specific intervals within a borehole, while the DPSH is driven continuously from ground level to refusal. Both tests apply the same drive energy to probes with similar diameters.
