英文摘要：

In order to explore the internal temperature of spontaneous combusting waste piles varying with time and depth,the depth and time of waste piles spontaneous combustion was detected and early warned. The temperature field superposition is adopted to analyze its internal temperature field based on the heat conduction theory model. According to the real field simulation,the experimental data are analyzed and calculated with the temperature field model. The results shows that： the model can be used in analyzing and calculating the internal temperature field of spontaneous combusting waste piles,with easy operation. The error is controlled below 10 ℃,and the maximum error is 20 ℃. With a high precision,the model provides an important guide to detect and warn the firing location of spontaneous combusting waste piles.
