全国地震工程科学技术的重点科研项目“5米×5米双水平向地震模拟振动台”自1988年通过了国家部级鉴定以后, 国家地震局工程力学研究所即积极将此振动台投入到了各种科研试验项目的使用中。在1989年完成的10项试验项目中,振动台的先进设计和合理工艺使试验结果达到了预期目的。 After the key scientific research project of national earthquake engineering science and technology project “5m×5m double horizontal seismic simulation shaking table” passed the national ministerial appraisal in 1988, the Institute of Engineering Mechanics of the State Seismological Bureau actively took this shaking table into each The use of a research pilot project. Among the 10 pilot projects completed in 1989, the advanced design and reasonable process of the shaker table have achieved the expected results.
