摘要
为了评定某桥梁的技术状态,运用脉动试验的方法对一亩河桥梁进行动荷载试验,从测点的布设、理论值的计算、现场测试,得出了一亩河桥的自振频率的理论值和实测值,通过数据分析,最终给出了准确的技术状况评定,从而为保证该桥梁的正常运营及日常维护提供了可靠的试验依据。
To evaluate the technology state of a bridge, this paper used pulse test method for the dynamic loading test of Yimuhe Bridge, obtains the theory value and measured value of the frequency of its natural vibration from measuring points layout, calculation of theory value and site test, and finally gives the accurate technology state evaluation through data analysis, to provide reliable test basis for the normal operation and daily maintenance of bridge.
