【摘要】 研究通过对冰峪沟英那河小峪河周边6个测点的节理裂隙实测,整理统计6个测点共296条节理的走向、倾向等产状参数,绘制节理产状玫瑰花图;通过对研究区域卫星影像图及地质图进行图层叠加,解译研究区域断裂分布特征,结合节理产状系统地分析了冰峪沟地区构造发育特征。研究确定NNE向为研究区的主要断裂发育方向,兼有NE、NW向断裂发育,且研究区NNE向断裂发育时期要晚于分布相对较少的NE、NW向断裂,区域应力场表现为北西向的压应力和北东向的张应力。断裂分布区域岩石破碎强烈,易于风化形成沟谷,河流沿断裂破碎带侵蚀发育,区域地貌形态受地质构造控制作用明显。更多还原

【Abstract】 Through the measurement of the joint cracks of 6 measuring points around the Yingna River and Xiaoyu River in the Bingyu Vally, the research analyzes the occurrence parameters such as the trend and tendency of the296 joints of the 6 measuring points and draws the rosettes of the joints. By superimposing the satellite image map and geological map of the study area, the fracture distribution characteristics of the study area are interpreted, and the tectonic development characteristics of Bingyu Vally are systematically analyzed in combination with the joint occurrence. The north-north-east(NNE) direction is identified as the main direction of the study area, including both north-east(NE) and north-west(NW) fault development as well, and the development of NNE fault in the study area is later than that of NE and NW faults with relatively less distributions. And the regional stress field is represented by the northwestward compressive stress and the northeastward tensile stress. The rock of the fault distribution area is strongly broken and prone to weathering and forming valleys. The river is eroded along the fracture zone, and the regional geomorphology is obviously controlled by geological structure.更多还原
