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。
This article briefly introduces the experimental research on the seismic performance of Gezhouba Erjiang pier. These include the self-vibration characteristics of the pier structure, the mode stress and the determination of various dynamic responses under the action of seismic waves. The effect of reservoir water on the structure has also been simulated. All experiments on the single pier, single span and the overall structure of three different situations, conducted a comparative test, a more comprehensive understanding of the superstructure and the connection on the various parameters. Finally, the test results made a brief analysis, summarized.
