    Abstract: 岩體變形行為主要受節理型態或節理力學 性質之影響,而體積不同之岩體所可能包括的 節理數量亦不等,以致岩體變形模數一般均隨 試驗試體體積之增加而變小,此一現象稱為規 模效應(Scale effect).在變形模數值不再隨所考慮 岩體體積大小而變時,稱此岩體為代表性基本 體積(REV)岩體.本研究擬利用一套已經室內縮尺 寸模擬岩體物理模型試驗結果驗證之岩體非線 性變形數學模式,透過對節理岩體變形性影響 因素的探討,期在各種節理型態下,決定真正足 以代表整體岩體變形行為之岩體規模.進而建 議現地岩體試驗之規模,並確立代表性基本體 積(REV)岩體與試驗岩體間變形模數之關係.
