    SEAL-ARCH GROUTING PROJECT PRACTICE OF CANGNAN TIECHANG RESERVOIR DAM

    • Cangnan Tiechang Reservoir was a backbone project of the Mazhan Plain low-yielding fields of planning. It mainly designed to flood control, water supply, combined with irrigation and power generation. The dam was designed as masonry arch dam. After the completion of the dam, due to various factors, there were much masonry joints and water-leakage in the vicinity, particularly serious up elevation 89 m.
