摘　　要：卫星探漏技术测定的供水管网疑似漏水区域范围既受当下卫星软硬件技术水平制约,也受破损管道埋藏环境、破损时间及漏水量等综合因素影响。其大小直接决定了暗漏点主动检出数量及效率。综合理论研究和实证分析得出在同时兼顾暗漏点检出数量和效率两个指标前提下,在国内城市以(125±25)m为其半径范围具有普遍适用性。The scope of the suspected leakage area of water supply pipe network determined by satellite leak detection technology is not only restricted by the current level of satellite software and hardware technology,but also influenced by comprehensive factors such as the burial environment of broken pipes,the time of breakage and the amount of water leakage.Its size directly determines the number and efficiency of active detection of dark leaks.In this paper,a comprehensive theoretical study and an empirical analysis conclude that the radius of(125±25)m is universally applicable in domestic cities under the premise of both the number and efficiency of dark leak detection.
