基于有限元神经元网络反分析侧压力系数的矿井有限元模拟分析

对岩土工程中岩土材料参数的不确定性进行了分析,从岩石力学系统的角度对工程中材料参数取值的不合理性进行了概述,提出从系统的角度对岩土的综合材料参数进行反分析,从而得到对实际工程具有应用价值的"综合参数".在利用神经网络的反分析矿井的侧压力系数的基础上后,利用大型有限元软件ADINA对矿井的受力和变形进行了分析,得出了对实际工程由一定价值的结论.

Based on Finite Element Neuron network Counter-analysis Lateral Pressure Coefficient Mine Pit Finite Element Simulation Analysis

The crag earth material parameter determinism has not carried on the analysis to the crag earth project in,material parameter value unfairness has carried on the outline from the rock mechanics system angle to the project in,proposed carries on the counter-analysis from the system angle to the crag earth comprehensive material parameter,thus obtains to the actual project has the application value "the comprehensive parameter".After the use nerve network counter-analysis mine pit lateral pressure coefficient foundation,use large-scale finite element software ADINA has carried on the analysis to the mine pit stress and the distortion,has obtained to the actual project by the certainvalue conclusion.
