新疆黑孜断层现今活动特征研究及有关问题的讨论
Active Fault’s Investigation and Discussion on the Correlative Question in Heizi,Xinjiang
【摘要】 在前人研究的基础上 ,用近年黑孜水库的形变测量资料重新计算了黑孜断层的微量位移 ,表明自 1973年以来黑孜断层活动特征发生了变化 ,大致经历了 4个阶段 ;其中第 3个阶段有正断层特征 ,其余 3个阶段属逆断层特征。水库大坝的修建及水库的蓄水对断层的现今活动具有重要影响 ,甚至改变了某个阶段断层活动的性状。地震活动对形变测量资料、断层活动也有一定程度的影响。
【Abstract】 On the base of other’s study, using the data of the deformation measurement, we calculate the tiny displacement of Heizi fault again. The result shows that,there is a change of fault’s activity since 1973. It can be divided into four phases: During the three phases, it has the thrust fault’s character, and the rest phase the normal character. The construction of dam and storage of the reservoir influence the fault severely, even change the fault’s local property. The seismic activity affected the data of deformation measurement and character of fault in a certain extent.
