| Abstract: |
| Using the precast concret wedge - shaped blocks to protect the stepped spillway, this will be not only economic and convenient in construction, but also safe and reliable. This paper has analysed theoretically the downthrpst force on the wedge - shaped blocks, and put forward a new calculating method, it has been confirmed by experiment results |
| Key words: stepped spillway,wedge-shaped block,downthrust force |
