Abstract
Complex loading and geometry conditions controlled the design of the shoring wall system at Benaroya Hall, the new home of the Seattle Symphony. A combined system, including three soldier pile and tieback walls and one soil nail wall, was used to shore an excavation that ranged from 15 to 50 feet deep. A 25-foot-wide block of soil remained between the soil nail wall face and an existing, underground bus station. Prior to designing the soil nail wall, a finite difference analysis was performed to determine potential movements of the station due to the excavation. The deflection estimates from the finite difference analysis closely approximated the actual field measurements obtained from inclinometer readings and optical surveys during construction.

Shoring Analysis, Design and Construction at the Seattle Symphony's Benaroya Hall
St. Louis, Missouri
Complex loading and geometry conditions controlled the design of the shoring wall system at Benaroya Hall, the new home of the Seattle Symphony. A combined system, including three soldier pile and tieback walls and one soil nail wall, was used to shore an excavation that ranged from 15 to 50 feet deep. A 25-foot-wide block of soil remained between the soil nail wall face and an existing, underground bus station. Prior to designing the soil nail wall, a finite difference analysis was performed to determine potential movements of the station due to the excavation. The deflection estimates from the finite difference analysis closely approximated the actual field measurements obtained from inclinometer readings and optical surveys during construction.
