液化判别的应力法与刚度法之比较

应力法和刚度法是判别土层液化的两种重要方法。本文在简要介绍判别原理的基础上,对两者作了比较,並结合工程实例和饱和标准砂样进行了对比。在相同的条件下,两种方法分析所得的抗液化安全系数是不相同的。本文提出的结论,就如何正确应用这二种方法提供了依据。

COMPARISON BETWEEN STRESS METHOD AND STIFFNESS METHOD USED TO IDENTIFY LIQUEFACTION OF SOIL

Stress and stiffness methods are two important ones used to identify liquefaction of soil. On the basis of briefly describing their respective principles, a comparison is made between these principles and their identification' methods with four engineering examples and standard samples of sand. Different values for antiliquefaction safe factor are obtained under the same conditions. The conclusions given by this paper have basicly shown holy to use the stress method and stiffness method correctly.
