Geophysical testing is often used as part of a project’s initial site exploration phase and helps to provide supplementary information collected by observing multiple gaps.
Geophysical testing can be used to establish the stratification of tribal material, bedrock top profile, groundwater depth, soil type limitations, hard soil, and rock aggregation, and the presence of voids buried pipes and depth foundations. The data of geophysical testing should always be directly related to the information of the methods of search.
If you are a resident of India and looking for a geophysical service then “Wtsgeophysical” may be ideal for you. It is the best geophysical service in India. Although you can find many geophysical products by researching online, but if you are looking for the best geophysical products, then “Wtsgeophysical” is able to give you effective service.
Do you know the advantages and limitations of geophysical tests? If you don’t know, we can help you. For your convenience, we are going to discuss some of the advantages and limitations of geophysical here. So let’s get started.
Advantages of Geophysical Test
Geophysical testing provides some significant advantages and some disadvantages that should be considered before recommending the technique for any particular application. The benefits are summarized as follows:
Many geological tests are non-invasive and therefore offer significant benefits in the case of conventional drilling, testing, and sampling (e.g., gravel deposits, talus deposits) or where potentially contaminated soils may occur underground.
In general, geophysical testing covers a relatively large region, thus providing the opportunity to characterize large regions with the help of a few tests. It is especially suitable for projects that have a large length of length compared to the surrounding boundary (such as for the construction of new highways).
Geophysical measurements typically evaluate the properties of soil and rock in very small strains, usually providing information about the true elastic properties in the order of 0.001 percent.
In order to obtain data on a satellite, geophysical methods are considered to be relatively inexpensive while costs are considered to depend on relatively large parts on which data can be obtained.
What Are The Limitations of the Geophysical Test?
Most methods work best in situations where there is a large difference in hardness between adjacent subsurface units.
Normal stratigraphy has a harder material than soft material but it is difficult to develop good stratigraphic profiling
The results are usually interpreted qualitatively and therefore effective results can only be obtained by an experienced engineer or a geologist familiar with the specific testing method.
Specialized tools are required.
Final Thought
Though geophysical is something that most of people know. But very few of them have an idea of its advantages and limitations. In this article, we try to discuss what are the advantages and limitations of geophysical. Hopefully, our small effort will be helpful for all of you.
