  摘要针对含穿透性裂纹的损伤层压板，采用“两板”模型建立起机械连接修补结构有限元分析模型，分别计算补片大小、厚度、铺排方式以及连接件位置等修补参数对修补效果的影响。
• By finding the big penetrating crack in wangpu aqueduct upper frusta structure , the task group has adopted the integrated measures of chemical perfusion , carbonized fibre reinforcement and doping external surfaces to effectively reinforce the work , and improved the reinforcing techniques considering the characteristic of hydraulic engineering , made remarkable benefit in social , economic aspects
  摘要针对王铺渡槽上部墩柱结构出现的大开度贯穿性裂缝，经过全面分析和多方案综合对比，采用裂缝化灌、碳纤维加固、外表面刷涂水性环保型乳胶漆外墙涂料作为防护的综合措施对原工程进行有效的加固处理，并结合水利工程的自身特点改进了加固技术工艺，取得了显著的经济和社会效益。
• 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
  关于预制裂纹系对岩石破裂的影响，集中讨论了：空障碍体构造不能阻止主裂纹的扩展，反而会使岩石的破裂强度降低近一个量级；由于构造的不同，非穿透切口样品和穿透切口样品的声发射空间分布特点有本质区别，穿透切口样品的微破裂在切口两端发育，而非穿透切口样品的微破裂在切口两端之间切口前缘处发育，这用三维破裂理论可以很好地解释；含共线构造的岩石，裂纹外端的声发射分布与单裂纹构造中裂纹端部的声发射分布相似，裂纹内端声发射有密集分布，在应力达到一定水平时，内端部发生错断，而不是贯通。
