Join your peers for the next SEI Houston Chapter Luncheon Technical Session:


Continuing erosion caused by the Brazos River in Southeast Texas was threatening the stability of the Judge Jodie Stavinoha Bridge. An innovative retaining wall design consisting of tangent drilled shafts with supplementary seal shafts was used to limit further erosion and to protect the abutment and corresponding embankment of the Highway 99 bridge crossing. A tangent shaft wall was selected which included both 5.5 and 10-ft diameter cast-in-place concrete drilled shafts with depths of up to 130 feet and comprised both anchored and cantilevered wall sections. Supplementary seal shafts and steel sheet pile deadman wall structures were incorporated into the design. The initial design had to be revised when a record flood from Hurricane Harvey impacted the site during construction.
