毛家村水库放空底孔金属结构设备检测与评估研究
|
摘要
本研究针对毛家村水库放空底孔闸门服役超过50年且许多技术难题尚无先例可循的特点,建立了一套科学、合理的检测及评估方案。通过采用先进技术设备现场检测与利用检测数据安全复核计算,综合评估毛家村水库大坝放空底孔闸门的安全可靠性,确保闸门的安全运行。同时此次检测与评估提出了调整完善闸门安全运行的建议,确保了工程运行安全,同时对国内外其他类似工程的检测与评估具有重要的参考价值。
The venting bottom outlet gate of Maojiacun reservoir has been running for more than 50 years and many technical problems have no precedent to follow, according to these characteristics, a scientific and reasonable detection and evaluation scheme is built. Through the on-site inspection by using the advanced technology equipment and the safety review calculation by using the inspection data, the safety reliability of venting bottom outlet gate of Maojiacun reservoir is evaluated comprehensively to ensure the safe operation of the gate. At the same time, the paper puts some forward suggestions to adjust and improve the safe operation of the gate, which has important reference value for the detection and evaluation of other similar projects at home and abroad.
