Abstract

A seismic retrofit evaluation was conducted for the existing Interstate 57 Bridge over Illinois State Route 3. The bridge is located within the New Madrid Seismic Zone. It is about 919 m long, has 30 spans and was designed in the 1970s with minimal seismic considerations. The bridge has concrete filled pipe-pile foundations bearing in medium to very dense granular soils. The estimated bedrock acceleration at the site is 0.22g (AASHTO). For the given site conditions, liquefaction is probable and could reduce foundation capacity in the southern half of the structure. Initially, underpinning with pin-piles and soil improvement were the recommended mitigation design options at the south abutment. A re-analyses using estimated residual strengths in liquefied soils for stability analyses indicated soil improvement would be unnecessary at the south abutment. The cost of foundation retrofit using pin piles was estimated to be about $225-$365 per linear meter.
