GL-6000 Airforce Pilot-Training Centrifuge
Project Overview
On all of these highly sensitive projects, GeoStructures conducted test borings with rock coring, Shelby tube sampling, and sometimes geophysical testing (MASW and downhole seismic) to characterize the various sites in detail and obtain the necessary subsurface information for dynamic soil-structure interaction analysis. In addition to index and unconfined strength tests, resonant-column tests were often performed on undisturbed clayey soils to accurately measure the shear modulus and damping behaviors. Pulse velocity (compression and shear waves) tests were also carried out on intact rock samples to determine shear wave velocities.
Foundation blocks were proposed to support the various centrifuges based on the subsurface conditions and the magnitude of loading. Dynamic soil-structure interaction analyses were then performed by using powerful 3-D finite element programs such as Abaqus. The entire building and surrounding area including the machine pit and foundation were meshed in Abaqus/CAE. Transient/rotational loading from the machine was realistically simulated in the model.
The analysis provided real-time ground vibration level at various distances from the centrifuge. The results indicated that the ground vibrations were well-below the threshold level and that the proposed foundation block was adequate. The analysis also provided the stresses and strains in the foundation system, which were then utilized for the structural design of the foundation.
