Sep 01, 2021 Shake Table Tests on a Shallow Foundation on Liquefiable Soils Supported on Helical Piles, PEER Report 2021/07. Abstract: Extensive damage to buildings and infrastructure observed during past earthquakes resulting from the liquefaction of shallow saturated soil deposits underneath structures has demonstrated the necessity for further research in the area of liquefaction-induced ground

Jun 20, 2012 This paper presents Shake-Table testing and FLAC numerical modeling of liquefaction-induced large ground lateral movement and settlement, and pipeline behavior induced by soil movement. A series of laboratory Shake-Table experiments were performed using a model slope ground and model pipe buried under the crest of the slope in a box 1,800 mm

Sep 21, 2016 liquefaction behavior using shake table test. A test program consisted of total 19 tests conducted on saturated cohesionless sand with varying amount of non-plastic silt. The behavior of such silty sand in the relative density range 30 to 60% has been studied by subjecting the specimens to a specific acceleration of 0.54g

The liquefaction-induced ground displacement in sloped ground occurred during past earthquakes. Therefore, if liquefaction occurs in a seabed in front of a seawall, the slope may make displacement of the seawall increase. A shake table test of a large scale model was conducted in order to study seismic response of the seawall and the

Apr 24, 2018 The results shows that liquefaction decreases with the increase in relative density as expected. The criterion adopted for liquefaction is pore water pressure ratio ru = 1. Liquefaction behavior of Puthu Vypin sand was more than Chertala and Aluva sand. KeywordsLiquefaction, Excess Porewater pressure, Shake table test
