危岩主控结构面智能显现机理研究

危岩是典型的地质灾害类型之一,存在众多的结构面是其重要特征,灾害发生时,起主导作用的结构面只有一个,其它的结构面只是起到辅助作用。本文利用BP神经网络系统,在快速寻找危岩主控结构面方面做了一些尝试,首先将输入样本按照重要程度划分为四级,在实例的基础上选取了大量的训练样本后进行工程预测,结果表明,所建立的系统能够很好的揭示危岩主控结构面,在三峡库区的部分危岩工程治理中得到了成功应用,效果良好。结果对于危岩工程实践具有一定的参考和应用意义。

Study on Intelligent Displaying Mechanism of Control Fissure of Perilous Rock

Perilous rock is a kind of typical disaster and characterized by multitudinous structural planes;when the disaster happens,only one of the planes is the control fissue and the others are secondary.In this paper,the authors have done some attempts for rapid search of control fissure in engineering practice using BP neural network.Firstly,the input samples are classified by four levels according to their importance,a large number of training samples is selected based on the engineering examples to carry through the forecast,the results show that the system can distinguish control fissure all-right,it has been proved that the effect is quite well in some engineering works in the Three Gorges Reservoir region.So,it is an important reference and can be applied to the perilous rock engineering practice.
