Abstract: Changes of reservoir storage and sedimentation are concerned issues. Thus, rapid determination of capacity and sedimentation is required. In the review of reservoir capacity curve and sediment measurement of Shanxi hydropower station, the advantages of the multi-beam sounding system such as convenient observation, high speed, high accuracy and diversified results have been verified. By application of the multi-beam sounding system, the accuracy of analysis on reservoir calculation and deposition has been enhanced, providing reference for further operation and management.

Key words: multi-beam sounding system, reservoir capacity, sediment measurement

摘要： 水库库容和淤积量的变化是水利电力部门十分关心的问题。正确快速测定库容和淤积量对保证库区、大坝的安全和计划调度、发电等起着重要的作用。通过2013年温州市珊溪水库库容曲线复核与淤积测量项目，验证了多波束测深系统在水库库容测量中具有观测方便、快捷、精度高和成果多样化、直观性强等优点，对于水库库容计算和淤积核查分析的准确度有极大的提高。
