摘要
通过对不同时期、不同地点发生的地震液化现象的分析得知 ,几乎大多数的地震震害是由砂性土层的液化引起的 ,且随着研究的深入 ,得知地震时容易发生液化的土类为粘粒含量 <15 %的饱和砂性土。主要包括粘粒含量 <3%的饱和砂性土和粘粒含量为 3%~ 10 %的饱和粉土。
By analizing the earthquake liquefaction phenomenon happened in different periods and places,we know that almost the damage of earthquake is caused by sand soil liquefaction.And with the deeper studying ,we also realize that the sand easily liquefied in the earthquake is saturated soil,whose clay particle content is less then 15%. It includes the saturated sand soil,whose clay particle content is less then 3%,and power silt,whose clay particle content is from 3% to 10% .
