【摘要】 紫荆关断裂是保定西部山区区域性深大断裂,经过了多期复杂的地质作用,形成独特的地质构造,对区域地下水的赋存、运动、排泄规律起了明显控制作用。根据地质调查、钻探、压水试验等勘察资料,分析了紫荆关深断裂在燕川水库库区的构造特征、破碎带及其周围不同岩性的导水性,查明了燕川水库渗漏原因及渗漏部位,为水库除险加固提供可靠依据。更多还原

【Abstract】 Zijingguan fracture is a regional deep fault located in the western mountain area of Baoding.It formed a unique geological structure after more than a period of complex geological processes,such as compressive shear,transtension,and lift.It has significant controlling effects on the storage,movement,discharge of regional groundwater.According to the regional geological data from geological survey,drilling,and pressure water test,the tectonic characteristics,hydraulic conductivities in different areas and strata of Zijingguan deep fracture in the Yanchuan reservoir were analyzed.The leakage causes and positions of Yanchuan reservoir were analyzed,which can provide reference for the reservoir reinforcement.更多还原
