摘要
为了研究永城地区隐伏的断裂构造及其富水性特征,选用对称四极电阻率剖面法、测深法对新商断裂(永城段)的构造地质特征和地层特征进行勘查分析。研究发现,太平集断层通过30线测点382—402、26线测点366—426、22线测点394—420、18线测点448—460段,倾向向南,且倾角相对较缓;05线测点266—274、03线测点228—236段的视电阻率ρ_(s)剖面曲线的变化分别反映滦湖断层组、刘松园断层组的存在;18线测点440—460段存在灰岩破碎含水体,倾向南,倾角约为50°;26线测点404处,AB/2=1 360 m深度时,存在含水不太丰富的含水层,规模较小,倾向南,倾角为45°~50°。
For studying the concealed fracture structure and its feature of water-rich in Yongcheng area.The symmetrical quadrupole resistivity profile method and sounding method were used to explore and analyze the structural geological and stratigraphic characteristics of the Xinshang Fault(Yongcheng section).Research has found that the Taipingji fault passes through measuring points 382-402 of line 30,measuring points 366-426 of line 26,measuring points 394-420 of line 22,and measuring points 448-460 of line 18,with a tendency towards the south and a relatively gentle dip angle.The changes in the apparent resistivityρ_(s) profile curves of the sections of measuring points 266-274 of line 05 and measuring points 228-236 of line 03 reflect the existence of the Luanhu Fault Group and the Liu Songyuan Fault Group,respectively.There is a fractured limestone aquifer in the section of measuring points 440-460 of line 18,dipping southward with an inclination angle of about 50°.There are 404 measuring points on the line 26,at a depth of AB/2=1360 meters,there is a relatively small aquifer with less abundant water content,smaller in scale,tilting southward with an inclination angle of 45°~50°.
