天生桥一级水电站隧洞开挖总长５．０６ｋｍ，为确保隧洞开挖质量并对其进行有效的控制，选用Ａ·ＭＴ３０００断面扫描仪对洞室开挖进行质量控制。该仪器由主机、红外线测距头、测量计算机组成，运用该仪器对隧洞开挖断面进行测量，具有方便、快捷、测量数据采集准确的优点。在天生桥一级水电站隧洞的监理过程中，使用该仪器，为检查、控制、评价隧洞开挖质量及计量支付提供了准确的数据。
Tianshengqiao a hydropower station total length of 5.06km tunnel, in order to ensure the quality of tunnel excavation and its effective control, selection of A. MT3000 cross-section scanner for the quality control of excavation. The instrument consists of a host computer, an infrared distance measuring head and a measuring computer. The instrument is used to measure the section of tunnel excavation, which has the advantages of convenience, quickness and accurate measurement data collection. In the process of supervising the Tianshengqiao-1 hydropower station tunnel, the instrument is used to provide accurate data for checking, controlling and evaluating the tunnel excavation quality and measuring payment.
