Cyclic Rotation of Principal Planes to Investigate Liquefaction of Sands
The main objective of this investigation was to investigate the effects cyclic rotation of principal stresses. To do this, it was necessary to first build a testing device that would apply cyclic axial and torsional stresses to a hollow cylinder soil specimen in such a manner that there would be continuous and systematic rotation of principal stress axes and then to evaluate the performance of the device in a preliminary testing program. The objective was achieved by designing and building a new electropneumatic loading system for an existing hollow cylinder test chamber and by performing five consolidated-undrained hollow cylinder principal stress rotation tests on saturated specimens of Monterey No.0 sand compacted to 50 percent initial relative density. The confining pressure, sigma sub 3c, for each test was 1.0 kg/sq cm. The new apparatus operated in the desired manner and provided some interesting and possibly far-reaching results.
