The development of a more rational design procedure to predict not only ultimate tieback capacities in cohesive soils, but associated tieback displacements as well, requires a basic understanding of short-term and long-term tieback behavior. In view of the above, a series of full-scale and model tieback tests were conducted on instrumented and non-instrumented straight-shafted, postgrouted, and single-underreamed tiebacks anchored in different cohesive soils. In addition, laboratory shear strength tests were conducted on soil-soil samples and grout-soil samples to allow a better interpretation of field and model results. A better understanding of (1) the load-transfer mechanism of each type of tieback and (2) both time-independent and time-dependent component movements has led to the development of a physical model to describe short-term and long-term tieback behavior in a cohesive soil.
