Depend on the Shuibuya Water Control Project, the subject of study on the joint sealing structure and materials suitable to large deformation focuses on the study and proof of sealing structure and materials used in the high face dam at the level of 200 m high. The important progress has been gained in the following aspects of plastic caulking sealing structure, conventional sealing structure, GB new surface watertight, SR composite rubber bar watertight, bottom copper watertight, non cohesive sealing and composite sealing materials. It also proved that the adoption of this technology could meet the needs of the face rockfill dam with height of 200 m. This research result has also gained outstanding achievements in the application of other projects. It provides the technical basis for the construction of the face rockfill dam of the Shuibuya project and other face dams at the level of 200 m high.
