大量事实表明,震害的严重程度不仅取决于地震本身的强度和结构物抗破坏能力,还与建筑场地条件有直接关系。《建筑抗震设计规范》(GBJ11-89)提出以土层平均剪切波速定量划分场地类别的新方法,使场地类别划分更趋科学合理。笔者于1990年至1991年度对大庆龙南和马鞍山两个场地类别划分进行了研究,测定了场地剪切波速,并给出了场地剪切波速经验公式。
A large number of facts have shown that the severity of the earthquake damage depends not only on the strength of the earthquake itself and the ability of the structure to resist damage, but also has a direct relationship with the conditions of the construction site. The “Code for Seismic Design of Buildings” (GBJ11-89) proposes a new method for the quantitative classification of site categories based on the average shear wave velocity of soil layers, which makes the classification of site types more scientific and rational. In 1990-1991, the author studied the classification of the two sites in Longnan and Ma’anshan of Daqing, and measured the shear wave speed at the site, and gave the empirical formula of shear wave velocity at the site.
