Standard penetration test results

Leslie Youd , and others. To account for the length of the drill rod. SPT results are in-situ field measurements, and not as subject to sample disturbance, and are often the only test results available, therefore the use of correlations has become common practice in many countries. It can provide useful information in very specific types of soil conditions, but is not as accurate as a Cone Penetration Test. The sum of the number of blows required for the second and third 6 in.

Correlation between SPT-N value, friction angle, and relative density

Typical values are for sand, in loose clay and in compacted clay. Public Works Research Institute. This is driven into the ground at the bottom of a borehole by blows from a slide hammer with a mass of Also, it is highly affected by drilling and sampling operations. Send us an email to editor geotechdata. Standard Penetration Test blow counts do not represent a simple physical property of the soil, and thus must be correlated to soil properties of interest, such as strength or density. In certain circumstances, it can be useful to continue driving the sampler beyond the distance specified, adding further drilling rods as necessary. Leslie Youd , and others. Pros and Cons Although it is widely used, there are some important limitations that I have to mention. On-site Cone penetration test Standard penetration test Monitoring well piezometer Borehole Crosshole sonic logging Nuclear densometer test Static load testing. To account for the length of the drill rod. The borehole is drilled deeper and the test is repeated. Leave a Reply Cancel reply Your email address will not be published.

There exist multiple correlations, none of which are of very high quality. Pros and Cons Although it is widely used, there are some important limitations that I have to mention. However, this results in blow counts which are not easily converted to SPT N-values — many conversions have been proposed, some of which depend on the type of soil sampled, making reliance on blow counts with non-standard samplers problematic. Unsourced material may be challenged and removed. For more accurate data and resulting analysis of soil conditions that will be more useful for engineering purposes, a cone penetration test should be specified with minimal SPT field verification. If the samples are found to be unacceptably disturbed, it may be necessary to use a different method for measuring strength like the plate test.
