摘要
泸定水电站地处强震区。大坝抗震工程设计主要由坝体内1350—1382m高程问隔2m水平土工格栅．坝体内1365、1371m和1377m高程的水平抗震框格梁以及上、下游坝坡1365～1381m高程的抗震框格梁三部分组成。坝体内水平抗震框格梁在国内尚属首次使用。就抗震框格梁的设计优化及施工方法予以简单阐述，以供同类工程参考。
The Luding Hydropower Station is located at high seismic zone. The dam aseismic structures mainly consists of the horizontal geogrid between EL. 1 350-1 382 m with a interval of 2 m in dam body, the horizontal cellular aseismie beams in EL. 1 365, 1 371 and 1 377 m in dam body and the cellular aseismic beams in upstream and downstream slope between EL. 1 365-1 381 m. The horizontal cellular aseismie beams in dam body are firstly adopted in China. The design optimization and construction of aseismic beams are introduced herein for reference to similar projects.
