| Abstract: | Combining with the geological condition of one hydraulic dam site district on the Yellow River, several scenarios are discussed how to build the gravity dam in the soft rock foundation, especially in soft interlayer rock foundation. Several design schemes are selected to calculate the stress using material mechanics method and finite element method. The results show that the second scheme can meet the design requirement, and has no larger tensile stress in the dam surface and internal. |
