| 摘 要： | 混凝土坝老化表现在表层碳化、冻融、风化、内部溶蚀、冻胀、裂缝发育以及体积改变等.随着坝龄的增长,老化现象也越来越严重,结构安全度逐渐降低,最后超载系数接近或小于1,失去其使用功能.本文对混凝土坝老化现象进行分析,并对其安全评价进行探讨.

| Abstract: | The aging of concrete dams is manifested by surface carbonization, freeze-thaw, abrasion, weathering, internal corro-sion, frost-heaving, cracks, water erosion and et al. As time goes by, dam aging becomes serious and the overload coefficient gets close to 1 which means the dam is losing its function gradually. This paper analyzed the aging of concrete dams and evaluated dam safety, for reference. |
