蓄水初期坝体内部实际温度分布状态对高拱坝的安全运行具有重要意义,基于分布式光纤测温原理,运用sufer8.0绘图软件绘制各蓄水阶段的拱冠梁坝段实测温度等值线图,根据温度等值图可直观分析坝体内的温度场分布状态,并结合西南某高拱坝施工期及蓄水初期光纤实测温度资料,判断得出该高拱坝坝体温度场分布大致合理,温度控制措施合理有效。由此表明,基于分布式光纤测温方法简单、结果可靠,可满足实际现场运行监测需要。
The actual temperature distribution inside the dam during initial storage is of great significance for the safe operation of high arch dams. Based on the principle of distributed optical fiber temperature measurement, sufer8.0 mapping software is used to draw the measured temperature equivalent value of arch dam section According to the temperature contour, the distribution of the temperature field in the dam body can be intuitively analyzed. Based on the measured temperature data of a high-arch dam in the southwest of China during the construction period and the initial period of water storage, Reasonable, temperature control measures reasonable and effective. This shows that based on the distributed optical fiber temperature measurement method is simple, the results are reliable, to meet the actual needs of field operation monitoring.
