利用遥感图像资料 ,对疏勒河断裂中段活动性构造及其力学特征进行了解译与分析 ,确定了新构造应力场。在此基础上 ,根据断层地震的成因和地质力学理论 ,对活动性构造的应力状态、发震的力学条件 ,以及对甘肃北山核废物处置预选场的影响进行了探讨。 Using remote sensing image data, the active structure and mechanical characteristics of the middle Shulehe fault were interpreted and analyzed, and the new tectonic stress field was determined. On this basis, according to the genesis and geomechanics theory of fault earthquakes, the stress state of active structure, the mechanical conditions of seismogenic shock and the influence on pre-selection of nuclear waste disposal in Beishan of Gansu Province are discussed.
