The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a gravity dam arch foundation bearing plate structure suitable for a wide fault. The structure comprises a fault, a dam body is arranged on the fault, a reinforced concrete bearing plate is arranged at the bottom of the dam body, the bottom of the reinforced concrete bearing plate is located in the fault, and a dam heel reinforced concrete micro-arch replacement plug and a dam toe reinforced concrete micro-arch replacement plug are arranged on the upstream face and the downstream face of the fault correspondingly. And n dam foundation middle reinforced concrete micro-arch replacement plugs are arranged between the dam heel reinforced concrete micro-arch replacement plug and the dam toe reinforced concrete micro-arch replacement plug. The method has the advantages that the excavated volume can be greatly reduced, the arch effect of the arched beams is fully utilized to transfer loads to good bed rocks on the two sides, and the bearing capacity of the fault part is improved; and the wide and large bearing plate can also homogenize the load of the dam body, the load needing to be borne by the concrete plug is reduced, and the phenomenon of stress concentration at the bottom of the concrete plug is relieved.
本发明涉及水利水电工程技术领域，具体是一种适用于宽大断层的重力坝拱基础承载板结构。本发明包括断层，断层上设置有坝体，坝体底部设有钢筋砼承载板，钢筋砼钢筋砼承载板底部于断层内，在断层的迎水面和背水面分别设置有坝踵钢筋砼微拱换填塞和坝趾钢筋砼微拱换填塞，坝踵钢筋砼微拱换填塞和坝趾钢筋砼微拱换填塞之间布置有n个坝基中部钢筋砼微拱换填塞。本发明具有可以大大减小开挖量，充分利用拱梁的拱效应将荷载传递到两侧较好基岩上，提高了断层部分的承载力；宽大的承载板也可以将坝体荷载均化，减小了混凝土塞所需承担的荷载，减缓了混凝土塞底部应力集中的现象等优点。
