而後又採用cfd數值模擬的方法對溪洛渡水電站主變洞排風拱頂這種多股氣流匯流的長距離通道內的氣流流動進行了分析，提出了「虛擬分支」的概念和相應的網路基元模型，並回歸得到了溪洛渡水電站主變洞排風拱頂各個排風「虛擬分支」風量均勻系數以及阻抗的計算公式。By emptying the above mentioned theoris and conclusions, this paper introduces detailedly the whole process of the compare and selection of cangzhou city gongrong road canal bridge ' s plan, design calculation and check of structure. the internal force calculation of the bridge adopts the program of plane member system ( bricas ), and it was checked by the program of brcad
本文最後應用上述理論和結論，以大量篇幅詳細介紹了滄州市光榮路運河橋（下承式鋼管混凝土系桿拱橋）從方案比選到結構設計和計算、驗算的全部過程，以及施工中的要點，本橋內力計算採用平面桿系有限元計算程序， （交通部公規院的《橋梁設計綜合計算程序》 （ bricas4 . 0 ） ） ，並採用空間有限元程序（ brcad2 . 0 ）進行驗算。Then on the basis of calculating result from the prefigurative deviation control structure calculation, " rational data forecast processing about error adjust in prefigurative deviation control was made by the prefigurative theory of bp neural network and corresponding program and software matlab6. 1. at last via the data comparison with the practical survey data draw a conclusion : it is feasible for the construction prefigurative deviation control and error adjust used in pc rigid frame bridges to use the calculation model and program brought forward in this paper
同時，在對預應力混凝土剛構橋施工過程線形預拱度控制的結構計算分析的基礎上，利用bp神經網路的預測理論和相應的程序及軟體包matlab6 . 1對預拱度控制中的誤差調整進行了較好的預測處理，通過與實際施工數據及成橋后測量結果作分析比較，得到結論：運用本論文的計算模型和程序對預應力混凝土剛構橋預拱度控制過程進武漢理工大學碩士學位論文行結構分析和誤差調整處理是可行。Because the prediction accuracy of ann and fuzzy system algorithm is insufficient for underground powerhouse rock surrounding stability, the method of accurate online support vector regression ( aosvr ) was applied to study the evolution law for underground powerhouse rock surrounding displacement
摘要針對目前廣泛使用的模糊系統和神經網路預測方法在地下結構圍巖變形預測中的缺陷，提出一種精確在線支持向量機（ aosvr ）並將其應用到水電站地下廠房開挖過程中頂拱圍巖的變形預測。Two - way arch bridges have big weight in existing bridges in our country, they have large quantity & locate all over the country. for some reasons, they behave aging & diseases. for the purses of assuring transportation safety, highway salibility, having the existing bridges to be used sufficiently & using the maintain money properly, it is necessary to do proper reliability evaluation for two - way arch bridges. consultes on the base of large quantity of domestic & foreign literature, this thesis uses engineering survy & others " evaluation experience & advances factors analysis & system synthesis method for two - way arch bridge. this method overcomes the shortcomings & abuses that the used methods have. it has high veracity, strong adaptability & good maneuverability
為了保證公路暢通、行車安全，充分發揮現役橋梁的作用，合理使用橋梁的維修加固費用，需對雙曲拱橋的可靠性做出恰當的評估。本文在大量參考國內外文獻的基礎上，結合工程調查和前人評估經驗，提出了雙曲拱橋可靠性評估的因素分析和系統綜合法，克服了過去各種方法的不足和弊端。該方法準確性高、適應性強、可操作性好。Double arch bridges are the most models of arch bridges built in our country in 1960s. beacaus of the merits in this structure, such as novelty, legerity, saving material, convenient for construction, they spread all over the country and was applied in a large quantities. they made a great contribute for the development of our country ' s highway and bridge causes
雙曲拱橋是我國20世紀60 ? 70年代建設最多的一種拱橋型式，由於這種橋梁具有結構新穎、輕巧、省料、便於施工等優點，一經出現便在全國范圍內得到大量的推廣應用，為我國公路橋梁事業的發展做出了重大貢獻。分享友人
