为了研究给高层建筑等造成巨大灾害的长周期地震动的对策,日本科学技术厅将用四年时间对国立防灾科学技术中心的大型振动实验台进行大规模改进,以使其能够产生大幅度的振动,从而探索大型设施的地震对策和在松软地基上发生的液化现象的机制等。
In order to study countermeasures against long-period earthquakes causing huge disasters such as high-rise buildings, the Japan Agency for Science and Technology will make large-scale improvements over the large-scale vibration test rigs at the National Disaster Prevention Science and Technology Center over a four-year period to enable it to generate significant So as to explore the earthquake measures of large facilities and the mechanism of liquefaction occurring on soft ground.
