  •   本研究依據周威霆(2012)所設計的一套III型斷裂韌度量測試驗,針對含邊緣裂縫之砂岩試體受反平面剪力情形進行研究,搭配陳志豪(2009)所推導之理論公式求取III型斷裂韌度。本研究之實驗條件為無圍壓及簡單荷重加載下進行III型斷裂試驗,且針對試體受高溫後之性質改變為變數條件來加以探討。
      本研究發現,以此方式進行III型斷裂韌度之量測,為可靠且穩定。砂岩經歷溫度在200℃前,試體強度會提升,之後呈現下降,到了600℃,下降趨於平緩。隨著燒結溫度的提升,單壓強度、動態楊氏模數、動態泊松比與III型斷裂韌度皆有下降之趨勢。

    A loading fixture proposed by Chou (2012) to measure the mode III fracture toughness (KIIIc) of gypsum samples has been adopted in this study. The testing specimens of this study were sandstone rocks which were assumed to be homogeneous and isotropic. The circular rock disks with an edge crack were prepared to be under anti-plane shear loading condition. The mode III fracture toughness test was achieved without confining pressure and was applied by a simplistic loading condition. This study uses the formula suggested by Chen (2009) to compute the values of mode III fracture toughness of the testing rocks.
    This study finds that the test proposed by Chou is a reliable method for measuring the mode III fracture toughness of sandstone rocks. The mode III fracture toughness versus temperature is observed in this study. When the temperature is less than 200℃, the mode III fracture toughness gradually increases. When the temperature reaches over 200℃, the mode III fracture toughness is declining. When the temperature reaches over 600℃, no apparent decrease in mode III fracture toughness is observed in the test.
