摘要
在工程场地地震安全性评价中,常常需要进行动三轴实验以测定土体的土动力学参数。本文介绍了四川省地震局的动三轴实验系统的组成以及其具体的操作和运用。经过两年多的运行,通过承接大量的土体动三轴实验,弥补了四川省地震局的技术短板,培养了一批专业的技术队伍,增强了单位的技术实力和市场竞争力,保持了单位在四川省行业内的领先地位和技术优势,产生了良好的经济效益和社会效益。
On the seismic safety evaluation of engineering sites,it is often necessary to carry out the dynamic tri-axial tests to determine the soil dynamic parameters. This paper introduces the composition and application of the triaxial experiment system. After two years of operation,through undertaking large soil tri-axial experiments. Our experiments for two years on line make up the short board of my unit technology,trains a group of professional technical team,enhances the unit＇s technical strength and market competitiveness,keeps the unit in Sichuan Province in the industry leading position and technological advantages,has a good economic and social benefits.
