以三峡电站#19机组充水保压蜗壳为例,基于典型断面(4-4断面)的蜗壳钢板应力计的监测结果,分别对施工期的充水加压、卸压,到首次调试运行停开机,再到后期正常运行阶段的蜗壳钢板应力进行了定性分析,并对后期正常运行阶段的钢板应力建立统计模型进行了定量分析,预测了蜗壳在一定时间内的运行情况,获得了蜗壳在各阶段受力的一般规律,证明蜗壳运行正常。 Based on the monitoring results of the volute gauge steel plate of the typical cross section (section 4-4) of the 19 # unit of the Three Gorges Power Station, the water pressure and pressure relief during the construction period were respectively adjusted to the first commissioning Run the machine to stop the machine, and then to the later period of normal operation of the volute steel sheet stress qualitative analysis, and the latter part of the normal operation of the steel plate to establish a statistical model for quantitative analysis of the prediction of the volute in a certain period of time the operation to obtain The volute at all stages of the force of the general rule that the volute is operating normally.
