水库水深测量精度直接关系到水库的防洪安全与蓄水兴利. 现有回声测深仪无法应对大水深施测的情况,且测量受到水库水温分层影响. 利用回声测深仪配合校正标进行大水深测量的校正方法,能够精确检测到回声测深仪水深测量的误差及差值、系统延时问题等,通过与各级校正标的真值比较、修正,能使测值近似真值,且使误差控制在容许范围内. 介绍了水深校正标基本原理、操作方法和步骤以及在水库测深中的应用.

The flood control safety and power generation is closely related to the water depth sounding accuracy of the reser-voir. The current echo-sounder can not be applied to the sounding of deep water and the results are affected by water tempera-ture stratification. The correction method of echo -sounder together with the correction mark can detect the measured error, difference and time delay of echo-sounder. The comparison of measuring value with the real value of all-level correction mark shows that the result is close to the real value and the error is within the permitted range. The basic principle, operating method, procedure and the application in sounding of reservoirs are introduced.
