摘　　要：本文利用陆地卫星ＭＳＳ，ＴＭ和航天飞机ＳＩＲ—Ａ遥感图像资料，对疏勒河断裂中段活动性构造进行了解译。通过对活动性断裂和活动性盆地力学特征的分析，确定了区内新构造应力场的主压应力方向为北东—南西向。根据断层地震的成因和地质力学理论，对活动性断裂所处的应力状态和发震的力学条件作出了概略估计，指出了疏勒河断裂东、中、西各段的应力状态各异，不具备发震的力学条件，发生较大地震的可能性很小。因而对甘肃北山预选的高放废物地质处置库址。,Based on the information of remote sensing images from landsat MSS ,TM and space shuttle SIR A, the interpretation on active faults in the middle part of Shule River is carried out in this paper.It is confirmed that the direction of main compressive stress of neotectonic stress field is northeast and southwest in this area by analyzing the characteristics of active fault and basin mechanics. According to the genesis of fault related earthquake and geomechanics theory, this paper studies the stress state of active faults and mechanics condition of quake formation.The difference of stress state among the east, middle , west part of Shule River fault shows that there is no mechanics condition for earthquake, and very little probability for big earthquake.Therefore, the pre selected high level nuclear waste disposal site in North Mountain, Gansu is safe from earthquake.
