砂土液化是一种重要震害现象。近年来,关于影响砂土液化各因素的研究愈发引人注目。但常用的实验及地质学方法,仅限于研究单一或少量因素与液化间的关系。而缺乏对形成砂土液化的多种条件的综合性分析。笔者采用数理统计的方法,对唐山地震时,影响砂土液化发生的十五个因素进行了综合性分析。初步认识了它们的相对重要性。
Sand liquefaction is an important earthquake damage phenomenon. In recent years, research on various factors affecting sand liquefaction becomes more and more noticeable. However, the commonly used methods of experiments and geology are limited to the study of the relationship between single and a small number of factors and liquefaction. However, there is a lack of comprehensive analysis of various conditions for the formation of sand liquefaction. The author uses the method of mathematical statistics to conduct a comprehensive analysis of the fifteen factors affecting the liquefaction of sand during the Tangshan earthquake. The initial understanding of their relative importance.
