The inverse theories and calculated methods of the material constant (damage degree) of damaged concrete media are studied using both of incident impulse signal and received impulse response.
Through actual examples, this paper analyses the concrete procedures of signal and electric centralized construction, which provides the reference for the technical transition of similar stations.
文章通过实例分析了信号电气集中过渡的具体步骤，为类似车站的技改过渡，提供了借鉴。

At the same time, destructiveness test by loading on simple supporting prestressing concrete beam and gathering work of the vibration signal were carried on.
