The mass that moves/vibrates during pile installation, i.e. weight of excitor block, hydraulic clamp and pile. Usually given in (kg). See illustration #11.
Dynamic method of analysis
The determination of the capacity, impact force, transferred energy, etc. of a driven pile, using analysis of measured stress waves induced by the driving of the pile.
Dynamic Pile Monitoring
The recording of strain and acceleration induced in a pile during driving and presentation of the data in terms of stress and transferred energy in the pile, as well as of estimates of capacity, impact force, hammer rise, etc.
Rods or cables installed into the adjacent soil mass or rock. Portion beyond zone of active pressure is pressure grouted to hold a soldier pile or similar walled excavation. The anchors may be installed horizontally or at a slope. See Appendix C.
Earth Auger
1. A helically shaped corkscrew-like tool with a power driving head on top and cutting head on the bottom designed to bore holes in the earth by drilling, either with or without the supplementary use of water. 2. A hand operated soil sampler.
French: tarière
earth pressure
Normally used in reference to the lateral pressure or force imposed by a soil mass against an earth-supporting structure such as a retaining wall or basement wall, or on a fictitious vertical plane located within a soil mass. The coefficient of earth pre
French: poussée des terres
German: Erddruck
Spanish: empuje de tierras
Italian: spinta del terreno
Portuguese: impulso de terras
Dutch: gronddruk
eccentric loading
Load that does not bear axially on the pile, usually due either to the pile being driven out of plumb or plan location or the actual imposed load condition.
