    武汉地区地震效应影响研究

    STUDY ON THE INFLUENCE OF EARTHQUAKE IN WUHAN AREA

    • 摘要: 虽然武汉市地震影响及地震危险性的水平较低 ,强震也不是武汉市工程地质环境的主要问题 ,但在城市生命线工程和高层超高层建筑方面必须考虑单体抗震设防。而且 ,随着武汉市城市建设的不断发展 ,地震效应影响逐渐成为武汉市工程地质环境评价的一个重要因子。文章在分析了武汉地区地震动衰减规律 ,进行了地震危险性评价 ,深入研究了各土层动力参数性质的基础上 ,指出武汉地区地震地面破坏主要存在砂土液化和软土震陷两种型式及各自可能的空间分布.

       

      Abstract: The level of seismic effect and earthquake risk is rather low, and far intense earthquake can not be a main geological problem with engineerng projects in Wuhan area, but the earthquake resistance measures must be considerded in constructing urban lifeline and superior buildings. With the unceasing social-economic development in Wuhan, the influence of earthquake becomes gradually a rather important factor in engineering-geological environment evaluation. After the research on seismic ground motion attenuation regularities we make an evaluation of earthquake risk and analyze the dynamic parameters of soil layers in Wuhan area, and then point out there exist two main types of ground failures by earthquake in Wuhan area: liquefaction of sandy soil and collapse of soft soil layer, and their possible spatial distribution is put forward.
