葛州坝二江闸墩抗震性能的试验研究

本文简要介绍葛州坝二江闸墩抗震性能的试验研究。其中包括闸墩结构的自振特性、振型应力以及地震波作用下各种动力响应的测定。库水对结构的影响也进行了模拟试验。全部试验就单墩、单跨和整体结构等三种不同情况,进行了对比性试验,较全面了解了上部结构以及联结方式对各种参数的影响。最后,对试验结果作了扼要分析、归纳。

RESEARCH ON THE TEST OF EARTHQUAKE RESISTANCE OF ERJIANG SLUICE PIERS OF GEZHOU DAM

This paper introduces briefly the test of earthquake resistance of Erjiang sIuice piers of Gezhou Dam which includes the determination of self-vibration of pier structure,the stress of vibration model,and the dynamic responses under seismic waves.The influence of reservior water upon the structure has also been considered.By comparing the three different situations(single pier,single span,and whole structure),the test has made a comprehensive understanding of the effect of the structure and connexion mode on various parameters.some analysis and summarization are given in the paper.
