应用带有偏差单元的IRN模型评价土坝的病害缺陷

Application of the IRN model with the error unit to the evaluation of the earth dam defect

对土坝的病害缺陷的评价方法进行了探讨,结合水利部颁布的《水库大坝安全鉴定办法》和大坝安全鉴定工作的特点,提出运用人工神经网络中带有偏差单元的IRN(InternallyRecurrentNet)模型进行土坝的病害缺陷评价的新思路。通过实例验证,该模型可达到较好的效果,具有一定的可操作性。为今后土坝的病害缺陷评价提供了可供借鉴的方法。

The method for the evaluation of the earth dam defect is discussed in the paper. Based on the characteristics of dam safety appraisal and the Reservoir Dam Safety Evaluation Method promulgated by the Ministry of Water Conservancy, a new model of artificial neural network,the Internally Recurrent Net(IRN) model with the error unit,is proposed and applied to the evaluation of the earth dam defect. The actual examples verify that the model is ideal and the new method is practicable and beneficial to the reasonable evaluation of the earth dam defect.
