浅论京九铁路河北段沿线地区活动构造卫星影像特征
|
摘要
京九铁路河北段地处冀中平原，沿线地区是新生代强烈拗陷区，活动构造发育，本文应用ＴＭ图像对全区的活动构造进行了系统解译，文中重点研究了活动构造的区域分布特征。探讨了区内活动断裂对水系地貌及地震震源深度的控制。对活动断裂的深部变化，运用地震层析（ＣＴ）资料加以推断和论证。指出了河北平原是重要的活动构造单元，该构造单元内地壳厚度薄，大地热流值高，今后工业布局必须考虑活动构造对地壳稳定性的影响
Jingjiu railway in Hebei section is situated in Jizhong plain, where is peripheral depression of the Cenozoic Era, and there are a lot of active tectonics. This paper gives the interpretive results of the active tectonic by using remote sensing image. In this time, a number of tectonics of NWW direction in all region are interpreted. The paper puts the stress on the scattering feature of active tectonics and approach the active tectonic's controling function to stream system geomorphy as well as the depth of earthquake source. The active tectonics changing in the depth is infered and proved by using CT data. At last, it points Hebei plain is one of the most important active tectonic unit where the earth's crust is thin and the earth thermal current value is high, the influence of active tectonic to the earth's steady must be considered when the industries was distributed.
