An open experiment “Large-scale shaking table test which analyzed the seismic resistance of an abutment foundation built on liquefiable ground” was conducted at PWRI

Large-scale shaking table test was conducted on January 19, 2017, to analyze the seismic resistance of an abutment foundation built on liquefiable ground. The test was open to the media.

The test was conducted using a large-scale three-dimensional shaking table and a large-scale soil tank to study the effectiveness of reinforcement applied to a road bridge abutment foundation that was designed without liquefaction effect.

The test results show that the reinforcement has a positive effect on the seismic resistance of the abutment foundation, reducing the bending strain on the piles and the inclination of the abutment. A lot of media came to PWRI for this experiment.

※This experiment was conducted as part of “Enhancement of Societal Resiliency against Natural Disasters”, which is managed by the Japan Science and Technology Agency (JST). This is one of the tasks of the Cross-ministerial Strategic Innovation Promotion Program (SIP) which is led by the Council for Science, Technology and Innovation under the Cabinet Office.
