中文摘要:
      针对我国水工建筑物的老化病害状况和耐久性问题,介绍了水工混凝土建筑物混凝土质量与老化性状的常规检测方法和手段,并分析了各种方法的优缺点和研究应用进展。针对现场检测和安全评估中存在的突出问题和难题,研发了基于冲击弹性波的水工混凝土结构无损检测技术体系,包括弹性波层析成像技术、表面波法、冲击回波法及冲击弹性波测试混凝土动弹性模量技术。工程实践证明,该技术可为各类水工混凝土工程的健康诊断、修补加固及安全运行提供技术支撑。
英文摘要:
      Combining with aging condition and durability of hydraulic structures in China, the routine non-destructive testing methods and means of quality and aging properties of hydraulic concrete structures are introduced in this paper. Then, the advantages and disadvantages of various methods andresearch prog-ress are analyzed. In view of the outstanding problems and problems existing in on-site inspection and safe-ty assessment, we have developed a non-destructive testing technology system for hydraulic concrete struc-tures based on impact elastic wave, including elastic wave tomography, surface wave method, impact echo method and impact elastic wave test concrete dynamic modulus of elasticity technology. The engineering practice has proved that this system can provide technical supports for the healthe diagnosis, repair and re-inforcement, and safe operation of various types of hydraulic concrete projects.
