中文摘要：

声学多普勒水流剖面仪（ADP）近十余年来得到了较为广泛地应用。与传统测流仪器相比，它具有方便、快捷、经济、安全、数据准确、适应性强等优点。某隧洞已运行了12a，为了进行安全评价论证提供科学依据，测量了不同流量下的隧洞进、出口水位、流速等参数。结合该工程实例介绍了ArgonautSL的应用，以及洞内水位测量方法。

英文摘要：

ADP is used widely in test in the last 10 years. Compared with the traditional apparatus, ADP has many virtues, such as convenience, shortcut, economy, security, nicety, good adaptability, etc. A certain tunnel has run for 12 years. For estimating its security, we must measure some parameters, e. g,, water level and flow velocity on the different cases of different discharge. Combining with the case, the appliance of Argonaut SL and the method of measuring water level in the hollow tunnel recommended.
