Embankment Slope Stabilization with Drilled Shafts at HAM-275-7.02 in Cincinnati, Ohio-PPT Presentation

PPT Presentation

Pdf Summary

The presentation describes stabilization of a failed embankment slope at HAM-275-7.02 in Cincinnati, Ohio, using drilled shafts. The project evaluation drew on pre-failure cross-sections, boring logs, inferred soil properties, inclinometer records, and later survey data. Verification borings were used to establish the depth to rock.<br /><br />Slope stability was assessed with several software packages, including GSTABL, SLOPE/W, and UA Slope. Drilled-shaft loads were evaluated with LPILE, and the design used a single row of shafts with reinforcement concentrated on the tension side. Construction required benching for shaft installation and careful positioning of reinforcement cages and inclinometer casings to support continued movement monitoring.<br /><br />Monitoring results were presented for inclinometers at shafts 9, 22, and 31, though the slides provide no specific measurements or conclusions about performance. The presentation identifies key considerations for successful stabilization: reliable inclinometer geometry, accurately locating the top of rock, understanding local geology, and obtaining access to the middle of the slope. Drainage, reinforcement configuration, and design-build procurement were also raised as discussion topics.
