摘要
分析了地脉动的形成机理,指出对场地地脉动有影响的是体波和面波,两者对场地地脉动影响与场地及周围环境条件有关,并提出场地动力特性测试时应注意事项,从而为地脉动更好的服务于工程场地动力特性测试奠定了基础。
This paper analyzes the microseism forming mechanism,and points out that body waves and surface waves influence the field microseism and their impacts on field microseism are relating to surrounding environment,and mentions matters needing attention in field dynamic characteristics test.Thus,it has laid a foundation for microseism better serving project field dynamic characteristics test.
