| 為了觀察台北市的土壤經過水泥改良後的動態特性，本研究利用電腦自動控制之共振柱儀器來進行試驗。除了現地土壤之外，本研究使用水泥、高爐水泥和水泥添加水玻璃共十種配比方式添加於臺北土壤中。由試驗結果得知，現地土壤和水泥改良土的剪力模數隨著圍壓的增加而增加，但阻尼比隨著圍壓的增加而減少，現地土壤試驗性質受圍壓的影響比水泥改良土還大。現地土壤和水泥改良土的動態剪力模數隨著圍壓延時間的增加而增加，增加的幅度不大，阻尼比隨著時間的增加而減少。現地土壤和水泥改良土的動態剪力模數隨著剪應變的增加而減少，阻尼比隨著剪應變的增加而增加。試驗結果也顯示隨著水泥添加量的增加而正規化的動態剪力模數-剪應變曲線有向右移動的趨勢。 | ||

| In order to studythe dynamic properties of Taipei cement-stabilized soil, the resonant column tests was used tin this study. Besides the in-situ soil in Taipei the cement improved soils and other admixed were performed the resonant co;umn tests to study their dynamic properties containing shear modulus and viscous dampimg ratio. The results showed that the shear modulus of in-situ doil and cement improced soil increases with confining pressure, but this viscous damping ratio dexreases with confining pressure, The influence of confining time on dynamic properties is not much. Shear modulus decreases and increases above a threshold shearing strain. Form the result of this study, it is found that the threshold shearing strain increases with admixed od cement. | ||
