Tieback Supported Cuts in Overconsolidated Soils

Abstract

The performance of 11 tieback‐supported cuts is reviewed. The excavations were made in overconsolidated Gulf Coast soils in Texas. Excavation depths ranged from 27 to 64 ft (8.2 to 19.5 m). The measured performance characteristics are compared to observations made on internally braced cuts and other tieback‐supported cuts in overconsolidated soils. Tieback loads are based on measurements made during construction. Apparent earth pressures were computed and compared with published cases. Wall and ground movements beyond the excavations are presented and compared with published experience. Conclusions are presented for behavior and design considerations.
