砂土地震液化的不确定性判别法综述
|
摘要
通过对不同自由场地液化势估计的方法和公式进行总结和比较 ,发现剪切波速比其它波的波速更能反映地基岩土层的工作性能 ,剪切波速法近年来也逐渐受到人们的重视 ,这是因为其测定简便易行 ,且和场地分类可以共用 ,同时它既不影响钻孔周围土的性态 ,又较少受操作条件和方法的影响 ,判别精度同其它经验方法也同阶 ,是一个很好的经验判别公式。
Through summing up and comparing evaluation methods and formulas of li quefaction potentiality in different free fields, it is discovered that reflects work capability of ground terrane more than other wave speeds. In recent years, shear wave speed comes to be paid attention to by people because its measure is easy and it can be used together with the classification of fields. It doesn't influence the characteristics of soil around the drill and be less influenced by operational condition and methods. What's more, it's discriminant precision is at the same level with other experience methods, being a good experience discrim inant formula.
