摘要
下坂地水库地处高地震区,大坝基础覆盖层厚度达150m,且存在可能液化砂层和软土层,地质条件十分复杂,大坝抗震设计是工程设计的重点和难点。
Xiabandi reservoir is located in a high seismic zone and the overburden in the dam foundation is up to 150 m deep. Moreover, the geological conditions are very complicated with possible liquefied sand layer and soft soil layer. Therefore, dam seismic design is the focus and difficult point in the engineering design. The paper briefly describes the seismic design of Xiahandi reservoir dam.
