The Standard Penetration Test (SPT) is a common insitu testing metod used id in geetricical therininig to asses soil properties. Properly performing the testt and analizing it s results are essential el for consulate soil characterizatiogn and d foundatiogen design.

Előkészítés, hogy a SPT Test

Before chuting the tét the equipment it good condition and d calibated. Select the succate tet location based od on project requirements. Clear the area and prepare the borehole to a suquable depth, removing loose soil or debris.

Performing the SPT Test

The test contrives drivig a split- barrel sampler into the soil using a standardized hammers weight. The number of blows requid to advance the sampler a specific distance (usually 30 cm) i splided ats the N- value. Repeat the processe ats at at each tet depth.

Analyzing SPT rezults

Ez az N- value obtained from the te payte information about soil density and density. Higher N- valiete indicate denser orstromger soils, while lower value es insuest softer or looser soils. These results are used to classify soil type and inform design.
