Abstract : artifical intelligence methods are implemented to simulate thebehaviors of axially and laterally loaded piles using the field observation tests data obtain ed f rom the drilled shafts and driven piles. the optimal neural network model is deve loped using only simple input data of spt - n values and piles ' geometrical featu r es etc. the analysis for r. c piles of some projects is performed adopting the bp n n and grnn models respectively, and the obtained predicated results are compared w ith the data from conventional design method. it demonstrated the obvious advanta ges of neural networks in the design of pile foundations over the traditional me thods. this paper has an important practical significance and a referential worth iness in the design of pile foundations
文摘:根據鉆孔樁和打擊樁的原型試驗觀測的數據，運用人工智慧方法對橫向承載樁和軸向承載樁的工作特性進行模擬，並利用標準貫入試驗（ spt - n ）值和樁的幾何特性等簡單的輸入數據，開發出相應的優化神經網路模型;然後，運用反向傳播神經網路模型和廣義回歸神經網路模型分別對某工程的鋼筋混凝土樁進行分析，並將求得的預測結果與常規設計法的結果進行比較，結果表明神經網路方法比傳統方法有明顯的優越性，在實際工程設計中具有重要的參考價值和現實意義。A type of two layers pbg structure band stop filter with holes in the substrate is introduced in this paper, it detaches the substrate and microwave circuit, which solves the problem of placing microstrip line and helps to manufacture and amend, both the simulation result with hfss and measurement results are given out to identify its possibility
