以往得到的断层滑动速度函数是通过理论研究获得,其计算结果与地壳介质等因素有关.由于目前人们对地壳介质和震源机制研究的局限性,使得计算结果的准确性不高.在系统提出用多普勒效应计算断层滑动速度函数的基础上,以汶川地震余震为例计算了地震断层的滑动速度函数.结果表明,滑动速度函数具有迅速上升,相对缓慢下降的特点,与Hisacla的研究结果一致.用多普勒效应计算断层断层滑动速度函数的结果与地壳介质和震源机制无关,应该是一种有前途的计算地震断层滑动速度的方法.
The fault sliding velocity function obtained in the past is obtained through theoretical research and the calculation results are related to the crustal media and other factors.Due to the limitations of researches on crustal media and focal mechanism at present, the accuracy of calculation results is not high.When the system proposed Doppler effect is used to calculate the slip velocity function of the fault, the slip velocity function of the earthquake fault is calculated by taking the aftershock of the Wenchuan earthquake as an example. The results show that the slip velocity function has the characteristics of rapid increase and relatively slow decrease, which is consistent with Hisacla’s research The result of calculating the slip velocity function of fault with Doppler effect has nothing to do with the crustal media and focal mechanism, so it should be a promising method to calculate the fault slip velocity.
