  4. Barrier cracks cannot stop the extending of a fracture, and the strength of the sample is reduced by almost one magnitude because of the existing barrier cracks. there are great differences of ae distribution between specimens with non - penetrate crack and specimens with penetrate crack. as for penetrate crack, ae occurs near the two end of the crack, and for non - penetrate crack, crack, ae occurs near the two end of the crack, and for non - penetrate crack, ae occurs near the front edge of crack, which can be explained well by the theory of 3 - d fracture ; ae distribution near the outer part of collinear crack is similar with that of the end of penetrate crack, and inner part of collinear cracks will run - through with high loads

    關于預制裂紋系對巖石破裂的影響，集中討論了：空障礙體構造不能阻止主裂紋的擴展，反而會使巖石的破裂強度降低近一個量級；由於構造的不同，非穿透切口樣品和穿透切口樣品的聲發射空間分佈特點有本質區別，穿透切口樣品的微破裂在切口兩端發育，而非穿透切口樣品的微破裂在切口兩端之間切口前緣處發育，這用三維破裂理論可以很好地解釋；含共線構造的巖石，裂紋外端的聲發射分佈與單裂紋構造中裂紋端部的聲發射分佈相似，裂紋內端聲發射有密集分佈，在應力達到一定水平時，內端部發生錯斷，而不是貫通。
