摘　　要：在长距离调水工程中需要穿越河渠、道路,多采用渡槽、倒虹吸等输水建筑物形式跨越障碍物,而受到天然地质缺陷、施工质量不佳、生物破坏等因素影响,输水建筑物裹头渗漏是较为常见的问题。为有效解决输水建筑物裹头渗流问题,查找渗漏通道,通过充电法、高密度电法、地质雷达法3种方法,对某输水建筑物裹头渗漏点进行研究,探索出一条综合利用2种以上物探技术相互印证,快速、准确查找渗漏区域的方法,以期为同类型工程问题分析提供借鉴和参考。In long-distance water transfer projects,water conveyance structures such as aqueducts and inverted siphons are often used to cross obstacles when crossing rivers,canals,and roads.Due to factors such as natural geological defects,poor construction quality,and biological damage,head leakage in water conveyance structures is a common problem.In order to effectively solve the problem of water leakage in water conveyance structures and search for leakage channels,charging method,high-density electrical method,and geological radar method were used to study the leakage points of a certain water conveyance structure,and explore a comprehensive utilization of two or more geophysical exploration techniques.
