摘　　要：铁路跨越山河,在铁路的旧线改造中,准确测量水下地形是确保跨河铁路安全、高效运行的关键环节。传统的水下地形测量方法往往受限于天气条件、测量成本和时间效率,相较而言,无人船技术能够全天候、高效率的对大面积水下地形数据进行快速精确采集,以陇海铁路改造项目为例,测量渭河水下地形生产较高精度的大比例尺地形图,通过两种测量方式的对比,利用无人船技术测量大面积水域时作业效率明显提高,同时避免了人员涉水作业存在的危险,证明了该技术在铁路跨河河道水下地形测绘方面的应用优势,最后对该技术后续在行业领域内的创新发展进行了展望。Railways span mountains and rivers,and accurate measurement of underwater topography is a key factor in ensuring the safety and efficient operation of railway crossings over rivers.Traditional methods of underwater topography measurement are often limited by weather conditions,measurement costs,and time efficiency.In contrast,unmanned boat technology can collect large-scale underwater topography data quickly and accurately around the clock and with high efficiency.Taking the Longhai-Railway renovation project as an example,the production of high-precision large-scale topographic maps of the Wei River underwater topography was achieved.By comparing the two measurement methods,the use of unmanned boat technology significantly improved operational efficiency when measuring large areas of water,while also avoiding the dangers associated with personnel entering the water.This demonstrates the application advantages of this technology in the field of underwater topography mapping for railway river crossings.Finally,the prospects for the innovative development of this technology in the industry are discussed.
