基于RTK数字测深仪的水库容量计量研究

Research on Reservoir Capacity Measurement Based on RTK Digital Sounder

水库情况调查是我国水利普查的重点任务。乌鲁木齐共有32座水库,由于库底地形复杂,人工勘探很难掌握准确的水库容量。人工勘探不仅任务繁重,而且无法得出淤泥淤积量,这就限制了水资源的有效利用。目前,国外一般采用卫星定位和探测仪对水下地形进行勘探,勘探工作主要包括定位和探测。本文基于国内外研究现状,提出一种利用网络RTK(实时动态差分法)的数字探测技术,快速获得水下地形参数,并利用有限元软件构造精准的三维水下模型,从而有效地对水库容量进行计量。希望对今后水库容量的计量研究提供理论依据。

Reservoir condition survey is an important task in water census in China.There are a total of 32 reservoirs in Urumqi.Accurate reservoir capacity cannot be easily mastered by artificial exploration.Artificial exploration not only leads to arduous task on one hand,silt deposition amount cannot be obtained,thereby limiting effective utilization of water resources.Currently,satellite positioning and detector are generally adopted in foreign countries for exploring underwater terrain.Exploration work mainly includes positioning and detection.In the paper,a digital detection technology utilizing network RTK is proposed based on current domestic and foreign research status.Underwater terrain parameters can be rapidly obtained.Finite element software is utilized for constructing accurate three-dimensional underwater model,thereby effectively measuring reservoir capacity.It is expected that it can provide theoretical basis for measurement study of reservoir capacity in the future.
