摘要
分析了波动法测索力的原理,推导出了两端铰支条件下考虑横向刚度时计算索力的实用公式,通过测量索的横波波速与瞬态振动的频率阶数i即可算出缆索张力,指出了该方法测量精度较高,应用前景广阔。
It analyzes the principles of waving method,and deducts a practical formula that can calculate the tensility under the condition of two-ends gemel.Through measuring the waving rate and shaking efficiency grade i,it can calculate the cable tensility and can also points out this method is accurate and could use in a large range.
