ABSTRACT The Standard Penetration Test (SPT) is used worldwide and is perhaps the most common in situ soil test. A recent paper published in the June 2022 edition of Geomechanics News highlighted the use of the test in current New Zealand practice. This paper explores…
Abstract An issue faced by young geotechnical professionals is when to terminate the Standard Penetration Tests (SPT) when advancing a borehole during a geotechnical investigation. This issue commonly arises in the soil-rock interface zone where the ground mass is transitioning from a soil to a…
ABSTRACT Using a database of 230 co-located cone penetration tests (CPT) and boreholes with standard penetration tests (SPT) from sites across Christchurch, New Zealand, this paper assesses the applicability of a range of existing SPT-CPT correlations from international studies. Both simple linear CPT-SPT relationships…
During past major earthquakes in Christchurch, enormous damage to engineered structures and lifelines has been caused by liquefaction-induced ground failures. Standard penetration test is the most commonly used in situ test for soil characterization of liquefaction resistance. However this test has some limitations. A major…
