摘要
针对传统观测方法在山区复杂环境下水库水文泥沙监测中观测效率和数据精度受限的问题,本文提出了基于有人船载的水陆一体化测量技术方法,通过水文专用测船集成激光扫描仪、惯性导航装置、GNSS、单/多波束测深仪、水位计等观测设备,构建水库船载一体化测量平台,实现库岸带陆上地形、水下地形、水位和表面流速流向水文多要素一体化监测。经白鹤滩库区应用及数据精度分析表明,船载一体化测量系统外业观测效率提升了4.5倍,地形精度相对误差优于2%,水位精度相对误差优于1%。所提出的水文要素船载一体化测量技术是可行的,可快速、有效地获取复杂山区水库的水陆地形等水文要素。
To address the limitations of traditional observation methods in terms of observation efficiency and data accuracy for hydrological sediment monitoring in mountainous reservoir environments,this study proposes an integrated land-water measurement technology based on manned vessel platforms.By integrating laser scanners,inertial navigation systems(INS),GNSS,single/multi-beam echosounders,and water level gauges on dedicated hydrological survey vessels,we establish a comprehensive reservoir-borne measurement platform.This system enables simultaneous monitoring of multiple hydrological elements including littoral zone topography,underwater terrain,water level,and surface flow velocity/direction.Application in the Baihetan reservoir area and accuracy analysis demonstrate that the shipborne integrated measurement system improves field observation efficiency by 4.5 times,with relative errors of topographic measurement accuracy better than 2%and water level accuracy errors below 1%.The proposed vessel-based integrated hydrological measurement technology proves feasible for rapidly acquiring comprehensive hydrological data including complex land-water terrain in mountainous reservoir regions.
