Abstract
Dynamic Properties of Lightweight Cellular Concrete for Geotechnical Applications
Highlights
Construction on soft soils can pose a number of challenges for geotechnical engineers, including dealing with high amounts of consolidation settlement and low shear strengths, and bearing capacities
Mechanical properties of the lightweight cellular concrete (LCC) materials were measured with different static soil testing procedures, the details of those tests are not presented in this paper
This paper primarily focuses on the dynamic properties of the LCC materials
Summary
Construction on soft soils can pose a number of challenges for geotechnical engineers, including dealing with high amounts of consolidation settlement and low shear strengths, and bearing capacities. When these soft soils are located in seismic regions around the world, additional challenges arise, such as the amplification of seismic ground motions and, an increased structural demand on the infrastructure (Pradel and Tiwari 2015). These poor ground conditions are improved with the implementation of costly ground modification techniques. A few examples are the Silicon Valley Berryessa Extension in San Jose, Colton Crossing for the Union Pacific–Burlington Northern Santa Fe (BNSF) railroad in Colton, and the San Bruno Railroad Grade Separation in San Bruno (Teig and Anderson 2012; Pradel and Tiwari 2015)
