关于土的动力特性这一基本研究课题,黄文熙、西特(H.B.Seed)和理查特(F.E.Richart Jr.)曾先后倡导用动三轴仪和共振柱仪来研究土的液化、动强度及动弹性模量,阻尼特性。目前美、日、欧洲与中国都对土的动力特性及其影响因素、动力特性的测试手段作了较为广泛的研究。但以往的研究对象大都是天然土,对人工加固土的动力特性的系统研究目前还不多。灌浆是提高地基抗震能力、满足动力基础的要求的重要加固手段。对于
With regard to the basic research topic of soil dynamic characteristics, Huang Wenxi, HBSeed and Ferichart Jr. have successively advocated the use of dynamic triaxial and resonant column instruments to study the liquefaction and dynamic strength of soils. Dynamic elastic modulus, damping properties. At present, the United States, Japan, Europe, and China have conducted extensive research on the dynamic characteristics of soil and the testing methods of its influencing factors and dynamic characteristics. However, most of the previous research objects are natural soils, and there are few systematic studies on the dynamic characteristics of artificially reinforced soils. Grouting is an important reinforcement method to improve the foundation’s ability to resist earthquakes and meet the requirements of the power foundation. for
