When utilizing a wave Investigation program program to forecast pile behavior, you could possibly operate into info issues. If the particular hammer that you are making use of is not shown when you're coming into wave analysis info, make use of a hammer of the same variety. It ought to have an analogous Power rating and ram body weight.
Driving system troubles could be connected to low hammer effectiveness or cushion that is definitely as well comfortable. The soil could have increased strength, greater damping ration, or more substantial soil quakes than First screening expected.
