Reliability-based foundation design for transmission line structures: Volume 2, Critical evaluation of in situ test methods: Final report

Abstract

This study critically evaluates the use of in-situ tests for site characterization, with emphasis on exploration for transmission line structure foundation design. Site characterization for transmission lines differs substantially from that of many other structures. Transmission routes traverse large distances, and the large number of structures, the variations in geotechnical conditions, and the relatively small exploration allocations necessitate optimizing the costs and benefits associated with in-situ methods of soil testing. 46 figs., 52 tabs.
