Based on the characteristics of geology,geomorphy and geophysics associated with strong earthquake activities on the west of Urumqi district,Approach Cord-3 is used to do the pattern recognition on the potential focal zone west of Urumqi. The result indicated that the areas prone to strong earthquakes are mostly related to some fractures,especially on their end points,corner periods and intersections. The more numbers of such fractures, the more probabilities of strong earthquakes occurrence. The five...

Based on the characteristics of geology,geomorphy and geophysics associated with strong earthquake activities on the west of Urumqi district,Approach Cord-3 is used to do the pattern recognition on the potential focal zone west of Urumqi. The result indicated that the areas prone to strong earthquakes are mostly related to some fractures,especially on their end points,corner periods and intersections. The more numbers of such fractures, the more probabilities of strong earthquakes occurrence. The five regions which occurred earthquakes during 1943-1989 are determined to be the places with the probability of strong earthquake occurrence in future.

根据乌鲁木齐以西地区与强震活动有关的地质、地貌、地球物理等特征,应用cora—3方法对乌鲁木齐以西的潜在震源区进行模式识别,结果表明,容易发生强震的地区主要与断裂及其端点、拐点、交点有关,而且其数目越大判定为强震可能发生地点的概率越大,1943——1989年已发生地震的五个地区,均为未来可能发生强震的地点。

According to the definition for the spectral magnitude advanced by Duda and Nortmann, using the digital vertical displacement data recorded by 5 telecontrol stations in Jiangsu area and 13 groups of 0.5 octave band pass filters of which central period are 1.2 s, 1.0 s, 0.67 s, 0.4 s, 0.25 s, 0.147 s, 0.119 s, 0.1 s, 0.078 s, 0.065 s, 0.054 s, 0.047 s, 0.041 s respectively,the average velocity spectra of P and S wave of 54 earthquakes has been determined.And the synthetical fact f of each earthquake can be gotten.Change feature of corner periods of the velocity spectra of P and S wave and the f values with time are studied.The results show that the synthetical fact f of velocity spectrum of medium minor earthquakes changed from high to low with time during one year or shorter period before medium strong earthquakes which occurred in the duration of low f value.

从Duda和Nortmann提出的谱震级定义出发 ,利用江苏地区遥测台网的 5个台站记录到的 5 4次地震的数字化垂直向位移波形记录 ,采用 1 3组 0 .5倍频程的滤波器 ,计算了各次地震的P波及S波在不同中心周期处的平均速度谱值 ,研究了地震的P波或S波速度谱的拐角周期及综合因子 f值的时间变化特征 .结果显示 :中强地震发生之前 1年或更短的时间内所发生的中小地震 ,其速度谱综合因子 f值随时间的变化具有由高值向低值的变化趋势 ,地震发生在低 f值阶段

The response spectrum parameters of strong ground motion are extracted by an automatic searching procedure based on the principle of the minimum standard deviation and the relation of these parameters to magnitude of earthquake and distance from source is analyzed in this paper. The results demonstrate that for both rock and soil sites, the corner period and platform height of spectrum curve increase with magnitude getting bigger, but the corner period gets longer and the height gets lower with the increase of source distance. The mean value of attenuation coefficient in declining part of standard response spectrum is obtained about 1.5.

以误差最小原则,用自动搜索的方式对强地震反应谱提取特征参数,并分析了这些参数与震级和距离的关系。结果表明,在不同场地条件下,反应谱的特征周期和谱平台高度随震级的增大而增大;同时,随着距离的增大,特征周期增大,谱平台高度降低,下降段衰减系数平均值为1.5左右.
