Simulation results show that the method is very simple to application and has also a good precision. non - parameter neural network model of the cable - damper system is formatted. based on the damping force and responses for past time steps, responses at the next time step can be predicted accurately with the non - parameter model
3 、應用神經網路技術對參數識別和非參數化建模問題進行了研究，提出一種直接識別結構物理參數的神經網路識別方法，該方法演算法簡單，識別精度高；建立了拉索-阻尼器系統的非參數神經網路模型，該模型根據過去幾個時間步的阻尼力及結構響應能精確預測下一時間步的響應。In this paper, systematic numerical test have been carried out to study the stability of surrounding rock mass with different distribution of weak interbed, different distance between weak interbed and limit of excavation, different thickness of weak interbed, in the different confining coefficient and representational surrounding rock mass graded ii, iii, iv. all of the numerical modeling is plain - strain type with elastic - plastic constitutive law and mohor - coulomb failure criterion, through the integrated numerical analysis program final. plentiful numerical test results have been drawn via analyse the deformation, tensile stress region, plastic region of surrounding rock and the stress status of shot - crete
大量的工程實踐表明，軟弱夾層對地下洞室圍巖穩定性的影響有著決定性的作用，本文以大型數值模擬分析系統final為平臺，採用彈塑性應力應變關系和m - c屈服準則建立平面應變問題有限元模型，對軟弱夾層的分佈部位、分佈距離、軟弱夾層的厚度對圍巖穩定性的影響以及在具有不同側壓力系數的地應力場中和、 、類代表性圍巖中軟弱夾層對圍巖穩定性的影響進行了系統的數值試驗，研究得出了軟弱夾層對圍巖位移、拉應力區、塑性區以及噴射混凝土層內力等影響豐富的量化成果，以便直接為工程設計人員提供參考。
