[提要]  使用DDS-70微機(jī)控制電磁式振動(dòng)三軸儀，對(duì)邯鄲市區(qū)的飽和粉土進(jìn)行小應(yīng)變的動(dòng)模量和阻尼試驗(yàn)研究，分析了動(dòng)應(yīng)變、固結(jié)條件、初始剪應(yīng)力等因素對(duì)動(dòng)模量和阻尼的影響，并列出了幾種土體的試驗(yàn)結(jié)果，供比較和工程應(yīng)用參考。
[關(guān)鍵詞]  飽和粉土  動(dòng)模量  阻尼比  動(dòng)三軸試驗(yàn)

A DDS-70 electric-magnetic dynamic triaxial apparatus controlled by computer is used to determine the modulus and damping of soil in the small rang of strain. After a few affecting factors are studied and analyzed, the value of the modulus and damping of several soils are given as reference and comparison.
Keywords: saturated slity soil; dynamic modulus; damping ratio; dynamic triaxial test
