摘要
利用智能数据采集仪对某灌渠的渡槽进行了振动试验,并采用DASP-V10软件对采集到的数据进行了时域分析、自谱分析以及三维谱阵分析。结果表明:有列车经过时渡槽的振动剧烈,对渡槽的耐久性产生了不利影响。
The vibration experiment on the aqueduct of an irrigation canal is carried out with the intelligent data acquisition in- strument, while the time-domain analysis, auto-spectrum analysis and 3-D spectrum matrix analysis are made on collected data with the software DASP- V10 as well. The results show that the vibration of the aqueduct is severe when train passed, and then has an adverse impact on the durability of the aqueduct.
