中文摘要 | 本研究採用對雲林外海離島工業區水力抽砂回填料源區的土壤,在實驗室中模擬 現地水力抽砂回填系統試體準備,以獲取回填造地土壤之顆粒堆積特性。同時配合濕搗法利 用自行發展的氣壓式三軸試驗系統,進行一系列壓密不排水三軸試驗,探討不同細料含量、 相對密度、試體準備方式及試體尺寸,對於回填造地土壤穩定狀態線之影響,及評估狀態參 數與回填土壤工程特性參數間之相關性。由試驗結果顯示:細料含量對於回填土壤穩定狀態 線之位置與斜率具有顯著之影響,細料含量越多狀態參數有增加之趨勢。回填土壤之狀態參 數和孔隙水壓參數 A ��、破壞時軸差應力比 R ��、穩定狀態摩擦角φ '、最大剪力模數 G 等工程參數間具有良好之關係,可提供利用狀態參數評估回填土壤工程性質之依據。 |
英文摘要 | This study investigated the packing properties of hydraulic-filled sand through the experiment performed on the soil samples obtained from the Yun-Ling nearshore area that was prepared by laboratory simulation of hydraulic-filled system. A series of undrained triaxial test was performed on the samples prepared by the moist tamping method by using the self-developed large scale triaxial testing system. Thus, the influence of the fine content, relative density, sample preparing method and specimen dimensions to the state parameter of reclaimed soil can be studied. The relationship between the parameter of engineering properties and the steady state parameter of reclaimed soil were also discussed. It was indicated from the results that the slope and location of steady state line was significantly under the influence of the fine content. The value of state parameter tended to increase when fine content increased. It was also found that the pore water pressure parameter A ��, failure stress ratio R ��, friction angle in steady state φ ' and the maximum shear modulus G had steady relationship with the state parameter of reclaimed soil so that the state parameter may be applicable to evaluate the engineering properties of reclaimed soil. |
