目前国内对于地方震的参数测定,大都采用半计算半几何作图的方法。近年来,国内外对于台站布局,即台站的几何分布对测定地震参数的影响开展了研究。《近震分布》一书对台网布局提出两个重要问题:一是“死局”问题;二是布局与参数误差问题。台网布局如果不合理,仪器工作虽然正常,资料也连续可靠,但测定出的地震参数精度不一定高,因此,台网布局直接影响到观测的成果问题。现在结合山西已建成的测震台网,看布局中存在的问题。
At present, for the determination of the parameters of local earthquakes, most of them use the semi-geometric mapping method. In recent years, the influence of station layout, that is, the geometric distribution of stations on the determination of seismic parameters has been studied at home and abroad. The book “Near-Earthquake Distribution” presents two important issues to the network layout: one is the “deadlock” problem; the other is the layout and parameter error. If the network layout is not reasonable, the instrument work is normal and the data is continuous and reliable, but the accuracy of the measured seismic parameters is not necessarily high. Therefore, the network layout directly affects the outcome of the observation. Now with the completion of the seismological network in Shanxi Province to see the layout of the existing problems.
