See Chinese contents: SL 282-2003 SL 282-2003: Design specification for concrete arch dams
This Specification is applicable to the design of concrete arch dam of Classification 1, 2 and 3 in water resources and hydroelectric hubs. For the design of concrete arch dam of Classification 4 and 5, this Specification can be a reference. For the dam over 200m high or the arch dam project under special situations, special study shall be done. According to the height, concrete arch dams can be divided into low dam, medium dam and high dam. Low dam is less than 30m, medium dam is between 30m and 70m, and high dam is over 70m. According to the thickness to height ration, concrete arch dams can be divided into thin arch dam, medium thick arch dam and thick arch dam (or called as gravity-arch dam). For thin arch dam, the thickness to height ration is less than 0.2. For medium thick arch dam, it is between 0.2 and 0.35. And for thick arch dam, it is over 0.35.
