The Study on Crack Prevention and Durability Measures for Concrete Face Slabs of Super-high Concrete Face Rockfill Dams
This paper focuses on the crack prevention and durability of concrete face slabs in super-high Concrete Face Rockfill Dams(CFRDs).By reviewing previous engineering practices,it analyzes the reasons of cracking in concrete slabs and proposes protective measures to improve crack resistance and durability.The study demonstrates that techniques such as balanced dam body filling,pre-settlement control,flexible slab design,and surface coating protection can significantly reduce cracking while enhancing anti-seepage,abrasion resistance,and durability.The research provides technical support for the future construction of CFRDs ranging from 250 to 300meters.
