中文摘要
本文主要在探討細料對不同級配下沉泥質砂動態與靜態強度之影響。將前
鎮河砂篩成A、B 和C 三種級配，並將通過ASTM #200 之土粒作為細料，分
別控制混合料相對密度30%、50%、70%，細料含量0%、5%、15%、25%，
研究結果顯示土壤之內摩擦角和液化強度會隨著細料越多而降低，三種級配之
液化強度皆隨相對密度增加而增加。本文亦利用顆粒間孔隙比觀念，說明級配
對土壤強度之影響可能與細料在土壤的角色有關。
英文摘要
The main purpose of this study is to investigate the influence of fines
content on static and cyclic behaviors of silty sands with different particle gradations. Three types of soil particle gradations, which are classified as A, B and C, were performed in sample sands from the Cian-Jhen riverside in Kaohsiung. Meantime the fines requested are added to the testing sand passing through an ASTM No.200 sieve. The relative densities of the specimens were set by preparation at 30%, 50% and 70% respectively with different fines contents of 0%, 5%, 15% and 25%. The results showed that fine soil particles have a remarkable effect on the decrease of internal friction angles and liquefaction resistance, and the relative densities of the specimens also have significantly positive effects on liquefaction resistance. The paper utilized also the concept of intergranular void ratio to investigate the correlation between the influence of fines on liquefaction resistance for silty sands and feasible roles of fine particles within the soils.
