The utility model relates to an it enlarges foundation structure to be adapted to low high arch dam that becomes mould basis. The utility model discloses an aim at making the thrust influence scope of arch dam enlarge through enlarging foundation structure, the distributing of stress on homogenization arch dam and basis, reduce the stress value on arch dam and basis to reach and guaranteeing under economical rationality, the technological feasible prerequisite, can be in low purpose of building high arch dam in becoming the mould basis. The utility model provides a: this foundation structure has the high arch dam of constructing between left bank and right bank, and the arch dam dam body makes the dam body divide into a plurality of monolith through the arch dam transverse joint, and it has the low basic rock mass of mould that becomes to distribute in the basic section of arch dam dam body part through the exploration, and there is the low scope that becomes mould basis rock mass to arrange in the distribution and enlarges the foundation concrete structure, expansion foundation concrete structure and arch dam dam body one -piece casting, and the arch dam transverse joint extends to the bottom that enlarges the foundation concrete structure. The utility model is suitable for a build high arch dam in low change mould basis.
