摘要

The purpose of this paper is to present the effect of fines content on the evaluation of liquefaction potential while using Seed's method (1985) and Tokimatsu and Yoshimi's method (1983). The data used in the paper were obtained from holes bored at sites where liquefied during Chi-Chi Earthquake, 1999. The fines content of soil is the major influence on safety and stability and is the target of the above methods. Student t-Test results show that the factor of safety calculated by Seed's method and T&Y's method can be regarded as identical when fines content less than 35%. However, the results of T&Y's method will overestimate liquefaction resistance when the fines content is greater than 35%. An appropriate correction factor for fines content greater than 35% is proposed from back-calculated analysis using data from liquefied sites. The result show the proposed correction factor will improve the efficiency of liquefaction potential evaluation in the T&Y’ s method at high fines contents.
