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;由于構造的不同,非穿透切口樣品和穿透切口樣品的聲發射空間分布特點有本質區別,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布與單裂紋構造中裂紋端部的聲發射分布相似,裂紋內端聲發射有密集分布,在應力達到一定水平時,內端部發生錯斷,而不是貫通。 |
