| 摘 要： | 大坝温度分布特点是大坝系统复杂因素综合作用结果，分析具体因素来描述温度变化具有一定局限性。基于HURST指数建立了大坝温度分形模型。以石梁河水库温度监测资料为例，计算了大坝温度场的HURST指数及分维数，结果表明，分形模型能较好反映大坝温度变化。大坝温度的变化规律与空间分布有关，大坝上游温度自相似性较大；大坝中下游坝体自相似性较好，且与气候分形规律相近。

Study on HURST index of observation data for for dam temperature |
| |
| Abstract: | The temperature distribution characteristics of dam system is results of complicated factors, analysis of specific factors to describe the change of temperature was difficult . Applying for the fractal theory, based on the HURST index, established dam temperature fractal model. Taking the ShiLiangHe reservoir temperature monitoring data for example, calculate the temperature field of dam HURST index and fractal dimension, the results show that the fractal model can better reflect the variations of temperature. The temperature variation rule is related to spatial distribution ,the upstream temperature self-similarity bigger; Self-similarity of the middle and lower reaches is better, and is similar to the climate fractal. |
