摘要
规定是对电子液压振动台基础设计而编制的,经过一些大型振动台基础的测试,用各种方法分析比较,认为国家测试规范用点峰法分析的阻尼比偏低,提出用双峰法使其增大,比较经济合理,但比弹性半空间理论的小,不失安全。现以此编制规定,在兵器工业系统内部试用。只介绍阻尼比,其他从略。
This specification is edited for design of electron hgdraulic pressure vibrator foundaticn.According to testing many larger vibrator foundations,analysing subsoil damping ratio by various methods,and comparing with each other, the ratio being smaller and uneconomic is got by the point-peak method in state code for measurement,and being larger and eccnomic may be got by two-peak method presented by this specification.But the latter is smaller and safer than that got by semi-infinite elastic space theory.Then this specificafin is put into practice in ordnance industry.The mentioned ratio is presented only.
