As an example, one particular area of the internet site may have a ongoing incredibly seem rock layer with almost nothing blocking a pushed metal H pile or steel pipe pile from achieving its required bearing capacity on the rock but another portion of the website may need layers of rock not effective at carrying the demanded bearing capacity higher than the continual sound rock demanding the usage of drilled micro piles to penetrate the higher layers.
When drinking water is current in these voids, or in the "pores" with the soil composition, we have to think about the results of pore drinking water tension modifications for the duration of pile driving functions in order to comprehend our onsite observations.
