Liquefaction of a sloping deposit: LEAP-2017 centrifuge tests at Rensselaer Polytechnic Institute
Abstract A series of centrifuge tests of a sloping ground were conducted at Rensselaer Polytechnic Institute (RPI). These tests were used to monitor and assess the soil response, in terms of generated accelerations, excess pore water pressure (EPWP) and associated lateral spreading, as a function of variations in the dynamic input motion and soil relative density. This series of tests are part of the Liquefaction Experiments and Analysis Projects (LEAP-2017), an international effort to assess the repeatability and reproducibility of centrifuge experimental results, and verify and validate soil liquefaction numerical tools using the experimental data.
Highlights The effects of an additional input frequency component on the response of a liquefiable sloping deposit are investigated. The effects of relative density on the response of a liquefiable sloping deposit are investigated. An additional frequency component leads to milder dilative soil response. A deposit with lower relative density has higher susceptibility to liquefaction. Lateral spreading of tested deposits increases due to additional input frequency component or lower relative density.
