Design of Permanent Soil Nail Walls Using Numerical Modeling Techniques
This paper presents the numerical analysis completed for design of a 4,700-car underground parking garage located at the Microsoft Block C site in Redmond, Washington. The underground parking garage is about 335.3 m (1,100 feet) long in the east-west direction and 121.9 m (400 feet) wide in the north-south direction. The excavation and construction of the basement wall was completed using a permanent top down soil nail wall. Because of the length of the structure, the garage was designed as three separate sections with construction joints up to 152.4 mm (6 inches) wide in the east-west direction to accommodate the seismic movement of the soil as well as thermal expansion of the concrete. Permanent soil nails were utilized to resist the soil pressure and improve the seismic performance of the east and west walls. Finite element modeling was completed to estimate the seismic deformation of the east and west walls and to design gaps between floor slabs and the east and west walls. The purpose of the gaps was to prevent transfer of seismic soil pressures to the garage structure, hence, significantly reducing the number of the internal shear walls. Discussions on the effect of permanent soil nails on wall deformation and wall pressure under both the static and seismic conditions are also presented.
