摘要
松散的粉土粉砂受到震动时,产生的液化现象,对建构筑物有破坏性的影响,标准贯入方法判断液化是《建筑抗震设计规范》推荐的方法,其计算公式自89版以来有了3次改变,文章尝试从液化判断计算公式的改变分析当前抗震液化判别认识的进展。
The liquefaction occurs when the loose silt and sand is encountered the vibration and earthquake,which may lead to the destruction of buildings. In the national code 'Seismic Design of Buildings', the SPT method is adopted and recommended to judge the liquefaction, while the judgment formula is changed three times since 1989. In this paper, the cognition of sand and silt liquefaction judgment is discussed in the view of the evolution of judgment formula..
