ASCE Geo-Institute Technical Presentation
Dear Member,
Please join us on Tuesday, January 14th for our monthly technical presentation. This event will be held at Sufi Mediterranean Cuisine from 6:00 PM to 8:30 PM.
Deep Soil Mixing Design and Construction for Surface Fault Rupture Mitigation
Deep soil mixing ground improvement was used to mitigate surface fault rupture and liquefaction hazards for a pump station with wet wells up to 36-feet deep. Paleoseismic field investigations were performed to characterize the site, then deterministic and probabilistic fault rupture displacement estimates were made and used to develop design scenarios. The fault rupture mitigation design consisted of a solid block of DSM encompassing and protecting the pump station and its wet wells. Three-dimensional soil-structure interaction numerical modeling of the fault rupture scenarios was performed as part of the design. The analyses showed the fault rupture displacements could be diverted by the DSM and that satisfactory structure performance could be achieved. The presentation concludes with an overview of the DSM construction, and quality control and assurance.
