运用有限元热分析技术，建立贮木场原木楞堆平面模型。逐层分析火焰蔓延过程中，楞堆及其周围的温度分布。比较有限元分析所得温度与火场实测温度，获得相应偏差。结果表明：有限元可以较好地分析贮木场原木楞堆的表面火焰温度场，可直观了解原木楞堆火灾发展，为及时控制楞堆火灾提供理论依据。

With Finite Element Thermal Analysis technology, we established the plane model of log pile in log yard to analyze the temperature field of log pile and its surrounding’ s level by level during the flame spreading process of log pile.The rel-ative deviation was gained by analyzing results of the experiment temperature and calculated temperature.The finite element can be used to analyze flame temperature field of log pile in log yard effectively, and provide a theoretical basis for an intu-itive understanding of the fire development of log pile and timely control fire.
