| 摘 要： | 坝后背管在我国大型水电站中得到应用,但是这些水电站多数位于酸雨地区.酸雨经裂缝会对混凝土和钢筋产生腐蚀,使坝后背管使用寿命大大降低.因此,对坝后背管4种混凝土抗裂措施进行探讨后得出,采用人工间隙措施是一种较好的抗裂措施,值得推广.

| Abstract: | The dam back penstocks are used in large hydroelectric power stations, but most of these stations are located in the acid rain regions. In the cracks the concrete and the steel bars are corroded by the acid rain,and then the service life of these dam back penstocks is reduced greatly. Hence, four measures of concrete crack resistance for dam back penstocks are explored. |
