I've got a question about the usage of the pocket penetrometer(PP). Its come to my understanding that some geotechs do not use the PP when it comes to cohesive soil. They rely solely on the N values to determine the strength of cohesive material. Initially, I thought this was an industry...
It is more of an observation than an actual test. I was just curious as my boss is adamant that conventional spread footings must not be on material that we observed to be 'dilated'. I realize that this may be a very specific practice that's done within the southern Ontario region.
Haha, we...
From my understanding the soil is dilated either when you shake it the moisture would be seen on the surface and there’s a “wiggly” action when the soil sample is slightly twisted. It a little tough to describe but it’s the best I’ve got. So essentially the soil is prone to oscillate even with...
I am a junior geotechnical engineer and currently working on a proposed two storey school. The drilling has been finished for the school and the general soil profile is essentially a silt-dominated soil with some clay and sand from the existing grade to about 4m below. The 'N' values range from...
