应用三角座标液化分区图和标指液化率对粘性土液化的判别

THE JUDGEMENT OF THE LIQUEFACTION OF COHES IVE SOIL BY MEANS OF THE Ty IGONAL DIAGRAM OF LIGUEFACTION DIVISION AND THE PROBABILITY FORMULA OF LIGUEFACTION INDEX

本文以土的粒度成分为主要依据,运用三角座标液化分区图,对场地进行初步确定是否发生液化以及对需要判别区所采用的基本方法。应用指标液化率公式判别粘性士液化程度。该方法既考虑液化影响因素,又考虑影响因素对液化势影响的幅度。主要适用于评价浅埋轻亚粘土场基液化。

Based on granulamelric compsition of soil,this paper uses the trigonal Diagram of liquefaction division as a basic method to determine preliminarily whether a liquefaction will occure in the site snd the basic method to be adopted for the judgement area required. The probability formula of liquefactaon index is applied to judge the liquefaction degree of the cohesive soil.This method consider not only the different influence factors of liquefaction,but also the influence extent of these factors to liquefaction potential.It is most suitable for the judgement of the shallow-buried loam site.
