    本文採用殷宗澤雙屈服面模型與堆石流變的負指數變化關系式，研究堆石的應力與流變關系，並推導了相應公式。在流變參數確定方面，由於室內試驗的試樣尺寸、時間比尺和顆粒破碎很難模擬現場條件，根據室內試驗直接確定堆石的流變參數是困難的。

  6. This paper, based on collecting many empirical determinations of strength parameter for jointed rock masses all over the world, puts forward the improved empirical determination of strength parameters, that is to say, " size effect reduction factor " and " jointed rock reduction factor " of the intact rock specimen for the study on jointed rock mass strength parameter, and applies to the a typical location of the dam, which proves that this methodology is feasible and rational, and a new way for study of strength parameter in jointed rock masses is established

    在大量收集國內外節理巖體強度參數經驗確定方法的基礎之上，提出了改進的節理巖體強度參數經驗的確定方法，即對完整巖石進行「尺寸效應折減」與「節理化折減」的二次折減法，並應用於某壩址區工程實例中，所得的計算值與現場實測抗壓強度值接近，較以往的經驗確定方法更加準確，證明了節理巖體強度的降低是尺寸效應與節理化綜合作用的結果，為節理巖體強度參數的研究提供了一條新的思路。
  7. Most researchers working in rock field proposed that the hopkinson system be a ideal dynamic - loading equipment and the brazilian disc be a novel specimen. according to the above, this paper suggests a new method to test the dynamic strength and dynamic fracture toughness, firstly leads the cracked chevron notched brazilian disc ( ccnbd ) which was recommended by international society for rock mechanics ( isrm ) in 1995 in testing dynamic fracture toughness, which brings in a new way in dynamic testing for rock. it is expected that the work of this dissertation will provide important basis for the further research and application of mechanical behavior of rock

    結合巖石動力學領域普遍採用的動態加載設備即分離式hopkinson壓桿裝置和新穎的平臺巴西圓盤試樣，本文提出了一套測試巖石動態強度和動態斷裂韌度的新方法，並首次將國際巖石力學學會（ internationalsocietyforrockmechanics ? isrm ）於1995年推薦的人字形切槽巴西圓盤（ crackedchevronnotchedbraziliandisc ? ccnbd ）試樣引入動態斷裂韌度的測試中，為巖石的動態斷裂力學參數的測試找到了一條新的途徑。
