In situ Testing Procedure for Obtaining Dynamic and Cyclic Soil Properties

摘要

The purpose of the project is to bring to realization an in situ geotechnical testing procedure for providing reliable estimates of in situ cyclic and dynamic soil characteristics, including (1) resistances to liquefaction, degradation, and large deformations; and (2) undegraded, nonlinear, inelastic characteristics. The information provided is to be suitable for the advanced stages of the earthquake resistant design of critical systems. Researchers conducted laboratory tests using a prototype system. The procedure was found to be generally effective under controlled laboratory conditions and promising for field use.
