Abstract: Pressuremeter testing was used as an integral part in the design of the temporary tieback shoring wall for the Columbia Center office building in Seattle, Washington. Pressuremeter testing and finite element studies were performed for the shoring wall as the design of the wall was complicated by the 120-foot-deep basement excavation. This paper discusses a method for interpreting pressuremeter test results to provide more reliable values of elastic moduli.
