| 摘 要： | 渡槽在建成运行后,由于受到气候、氧化、腐蚀等因素的影响而自然老化,以及长期在静载或地震荷载作用下遭受的损伤,其强度和刚度会随着时间而降低,结构的性能会逐步恶化,从而影响其正常运行。从承载能力、表观缺损和主要承重结构耐久性损伤3个方面提出了梁式渡槽结构安全评价的指标体系与方法。

| Abstract: | After aqueduct structures are built,structure aging due to the influence of the weather,oxidation,corrosion,and the structure damage suffer from undering static load and earthquake load in the long term,the strength and stiffness does diminish as time goes by,properties of structures are becoming worse.As a result,that affects its ordinary operation as time goes by.This paper proposes index systems and methods for aqueduct safety evaluation from three aspects,loading capacity,visual defects,durability damag... |
