| Abstract: | As the flood discharge tunnel of Nuozhadu Hydropower Station is a hydraulic tunnel with high flow-velocity and large flow rate，the hazard of cracking from the concrete flow-surface of it is great，and then the adoption of the relevant anti-cracking technology is quite important. Through the methods such as reasonably layering and blocking，reducing restriction of foundation，controlling quality of raw materials，adopting comprehensive temperature control measures，etc.，the occurrences of the non-prearranged cracks are effectively avoided therein； which can provide some references for the similar projects concerned. |
