随着技术的发展,许多高新技术装备、生产线对场地环境要求越来越高,如上海光源等一些电子产品的工作平台对振动要求较为严格,因较大的振动会影响产品的质量。然而工厂通常处于一定的振动环境中,如何减小微振动往往成为工程成败的关键。研究表明,场地微振动是地面的一种稳定的非重复性的随机波动,与该场地的地质结构、气象、江 With the development of technology, many high-tech equipment and production lines have higher and higher demands on the site environment. For example, the working platform of some electronic products such as Shanghai Light Source has stringent requirements on vibration. Large vibration can affect product quality. However, the factory is usually in a certain vibration environment, how to reduce the micro-vibration often become the key to the success of the project. The study shows that the micro-vibration of the site is a stable, non-repetitive random fluctuation of the ground, which is related to the geological structure, meteorology,
