摘要
那吉坝址下伏基岩为新第三系红层，在水利水电工程中第三系红层属软岩，软岩作为坝基通常隐含着一系列特殊的工程地质问题，为此，必需改变泄水建筑物的结构形式来满足建坝条件并改善建筑物的运行环境，通过方案比较，最后选择驼峰堰覆盖层方案。
The underlying base rock of the Naji WRPP dam seat is new 3rd system red layer,it belongs to soft rock in hydraulic and hydropower engineering.There is a series of particular engineering goelogy problems for using soft rock as dam base,so the discharging building structure type must be changed to meet the need of constructing dam and improve the building's operating environment.By schemes comparition,the Naji WRPP finally chose hump weir blanket.
