| 中文摘要: |
| 对近年我国水利水电工程中有关水工混凝土建筑物的病害检测、评估与修补加固方面的新材料、新技术和新工艺等进行了综合性评述。水工混凝土建筑物因受环境、水荷载及温度变化等不利影响, 建成后往往带病运行, 运行后又有一个老化过程, 因此需要精心地检测、维护和修补才能保证其安全运行。实践表明, 许多预防老化病害的措施, 在设计和施工阶段就应认真考虑并实施, 在使用阶段应对建筑物进行定期检测, 对任何损坏予以及时修补, 以确保建筑物的安全使用并延长其使用寿命。 |
| 英文摘要: |
| This paper summarized the advances of novel materials, technology and techniques, which had been applied in the detection, evaluation and repair of the defect in hydraulic concrete structures. Hydraulic concrete structures are always affected by some environmental factors, such as water load, temperature etc. and may be in an ill operation condition due to aging, therefore it is necessary to carefully examine, maintain and repair the structures for their safe preformance. Pract ice indicated that some preventive measures should be considered and implemented during design and construction stages. If designers and builders had paid more attention to the aging problems, occurrence of accidients would be avoided or delayed. If examination and repair for structures could be regularly carried out, the lifespan of structures would be extended. |
