坝—水相互作用中水的压缩性影响研究
|
摘要
利用有限元软件ADINA,通过对几个坝水耦合的例子进行具体的分析,得出库水压缩性在坝—水相互作用中对坝体自振频率、振型和坝面动水压力的影响。
Through analyzing several examples of dam-water coupling specifically,the effects of the compressibility of water upon the frequency of natural vibration,vibration mode and the hydrodynamic pressure in dam-water interaction are obtained by using the FEM software ADINA.
