摘要
本文利用广东新丰江水库丰富的前震资料、用方向追踪法计算了水库区的b值.从b值的变化,初步定量地圈定了新丰江6.1级地震震源体上下界的大小;讨论了b值与小震震源深度;b值与震源机制、应力的关系,提出统计量b的分布函数应是一个二维函数,它与应力和介质温度有关,同时b值具有方向的变化.
In this paper, the B-value of reservoir region is calculated by the use of the fruitful tore-shock data of Xingfungjiang in Guangdongprovince and by the directional method. From the variation of B-value, the critical size of focal body of Xingfung-Jiang earthquake M = 6. 1 is originaly obtained and the relations of B-value with small seismic depth, focal mech-amism, stress are discussed. It is proposed that the distribution function of statistical quantity B is a two-dimensional function which bears relation to stress and mediun intensity, simultaneously, the B-value is variable in the direction.
