Experience on a standard penetration test

2021
The standard penetration test can perform the same function as exploration as well as survey and test. During the more than recent ten years, many departments in China have been engaged in studying on this subject, they have not only achieved good experience on application of S.P.T.

Energy Transfer in Standard Penetration Test

Journal of the Geotechnical Engineering Division, 1982
An expression is derived for the fraction of the kinetic energy transferred from the hammer to the drill rod in the SPT which reflects the energy loss attributable to drill rod length. The expression is used to study the effects of rod size, and the potential effect of reducing the hammer weight and increasing the fall height correspondingly.

The Dynamic Penetration Test: A Standard that is not Standardized

Géotechnique, 1970
Synopsis The Paper presents a description and a discussion of the technique of making the so-called standard penetration test as used in North and South America. Dynamic penetration tests such as the SPT are used widely in an effort to get results that can be interpreted by engineers on a universal basis.

Chemical Protective Clothing Standard Test Method Development Part 1. Penetration Test Method

American Industrial Hygiene Association Journal, 1988
A "round-robin" interlaboratory study was conducted to validate the relative precision of the American Society for Testing and Materials (ASTM) F-903 test method for measuring the resistance of protective materials to penetration by liquids. The study utilized seven independent laboratories performing three trials of five protective clothing materials ...

Field Correlation of Cone and Standard Penetration Tests

Journal of Geotechnical Engineering, 1986
In recent years, attempts have been made to correlate standard penetration blow counts with cone penetration tip resistance readings in order to utilize the large data base and experience of standa...

Drill Rod Influence on Standard Penetration Test

Journal of the Geotechnical Engineering Division, 1977
The many factors that affect the standard penetration test variability have been listed and examined qualitatively by Fletcher and others. One factor listed is the rod linking the split spoon sampler to the surface. Intuitively, one would expect the rod stiffness and inertia to affect the SPT resistance.

Standard Penetration Test: Its Uses and Abuses

Journal of the Soil Mechanics and Foundations Division, 1965
In foundation test borings, the recovery of soil samples with a 2-in. OD split sample spoon driven with a 140-lb weight falling 30 in. has been in use for more than 30 yr. Recording the number of blows required to drive the spoon 12 in. has been called the Standard Penetration Test. It provides an approximation of soil densities in situ. It adds little

Correlation of Standard Penetration Test Results with Vibracore Sampler Penetration Rates

1972
A correlation between the penetration rates of a vibratory underwater sampling device and blow counts from the conventional standard penetration test and the continuous-drive cone penetration test is described. Although limited test data are available, the correlation shows promise for low blow count underwater soil deposits. A practical example of the

Standard Penetration Test and Dynamic Cone Penetration Test Relationship for Coarse-Grained Soils

The Standard Penetration Test (SPT) is a commonly used and effective disturbed sampling in-situ method to obtain the strength characteristics of soils, providing significant results for geotechnical design. Several correlations between SPT blow counts (N value) and soil behavior have been established to define physical and mechanical properties ...
