It is a considerably faster and cheaper tool than boring equipment especially when the depth of exploration is moderate and the soils under investigation are soft or loose. 11365 4563 tehran iran e mail. The mackintosh probe is a lightweight and portable penetrometer.
This paper presents the capabilities of the mackintosh probe for the. One set of mackintosh probe equipment was used to investigate the bearing capacity of the untreated peat soil. It is a convenient method to use for any site inaccessible to conventional testing equipments. One set of mackintosh probe equipment was used to investigate the bearing capacity of the untreated peat soil.
The tool consist of high yield steel rods each of length approximately 120cm that are connected each other by 25mm outer diameter couplings with a 27 9mm diameter of a 30o apex angle. This test is very useful to find out the bearing capacity of soil upto 18 meter. The difference between the results of allowable bearing capacity based on the empirical method and mackintosh probe test for the site a and b are 2 5 and 2 7 respectively. Mackintosh probe test is most widely used in situ test to measure the soil bearing capacity of different layers in terms of n value.
The results reveal that mackintosh probe test as a conventional method seems to fit with seismic method in determining the bearing capacity of shallow foundation. A mackintosh probe is a lightweight portable penetrometer that is designed to be a tool to investigate the soil bearing capacity.
