What is dynamic sensing in geotechnical research?
During construction work, both natural soil and artificial embankments are most often the supporting layer for the foundations of structures. For obvious reasons, it must be characterized by precisely defined properties, in particular by the degree of compaction. This parameter should be set with the highest possible accuracy, which can be facilitated by dynamic sensing. What is worth knowing about this process?
How is dynamic sensing performed?
In relation to non-cohesive soils, which include sands, crushed stone and crushed stone, the degree of compaction is taken as the main geotechnical parameter. Its definition allows engineers to make very precise static calculations necessary during design. Dynamic sensing obviously requires the use of specialized devices. Nevertheless, the very principle of taking measurements, at least at first glance, may seem quite simple. What exactly are we talking about?
As a rule, dynamic probing consists in driving a conical tip of the appropriate design into the substrate using constant impact energy. As a result of the geotechnical survey, characteristic values are obtained corresponding to the number of impacts per unit of immersion, which ranges from 10 to 20 cm. The collected values and, above all, the correlations between them make it possible to determine the degree of compaction of the tested soil. Based on them, decisions are made regarding the next stages of work. What else is worth knowing?
Application of dynamic sensing
The great advantage of dynamic sensing is the versatility of this method. Although it is used in the vast majority of cases to determine the degree of compaction of loose soils, it also works well at many other levels. It is certainly worth emphasizing here that dynamic measurements are carried out as control tests during the formation of construction embankments. The test also becomes necessary when checking the layers of the road base, ballast for filling, road surfaces, foundations and ramps, as well as automobile and railway embankments. Soil checks should remain in place even after the construction of dynamic exchange columns and gravel piles is completed.
Thus, it can be clearly stated that one of the most important assumptions of dynamic sensing is to check whether the design requirements for the degree of soil compaction have been met.
