摘　　要：2023年7月,受台风“杜苏芮”影响,北京市遭遇特大暴雨,导致境内多条河流发生了超百年一遇的流域性特大洪水。在随后近三个月的抢险救灾过程中,面对突如其来的复杂工况及各类探测难题,采用以高密度地震映像为主的综合物探技术,及时开展适用性试验,总结高密度地震映像密实性探测的分析办法,并结合微动技术、地质雷达等多种勘探手段,成功应用在永定河、拒马河等流域的堤防隐患探测、冲蚀区密实性探测等实践中,为北京“23·7”流域性特大洪水应急抢险贡献了力量。In July 2023,under the influence of Typhoon"Dussuri",extremely heavy rainstorm will occur in Beijing,and several rivers in the city will experience basin wide catastrophic floods with intensity of more than 100 year return period.In the past three months of rescue and relief efforts,faced with sudden and complex working conditions and various detection difficulties,we applied high-density seismic imaging,conducted timely application experiments,and summarized the analysis method for highdensity seismic imaging density detection.This exploration technology has been successfully applied in the practice of eliminating hidden dangers in embankments,exploring water damaged areas,and detecting siltation and backfill materials in the Yongding River,Juma River,Xiaoqing River and other river basins.
