Wherefore, other two energy - based fracture parameters are put forward : the stable fracture energy gfs, indicating the average energy dissipation during the crack stable propagation and the unstable fracture energy gfu, corresponding to the crack unstable fracture stage. wedge. ? splitting specimens are tested with a view to understanding those two parameters " size effect in terms of the initial crack length a0
本文提出兩個能量型斷裂參數即穩定斷裂能g _ （ fs ）和失穩斷裂能g _ （ fu ）分別表示裂縫穩定擴展和失穩擴展階段的能量損耗，並採用楔入劈拉試件（ ws ）對這兩個參數相對初始縫長_ 0的尺寸效應進行了分析。 -
3. different test methods in determining those three fracture energy parameters arise one problem, that is whether gf. gfs and gfu are consistent as obtained from different measuring methods
由於測試混凝土三個斷裂能參數採用的方法不同從而帶來了一個問題，即不同的測試方法所得到的g _ f 、 g _ （ fs ）和g _ （ fu ）是否一致
