2 )設計吊桿式拱架支承結構時,各部分構件應當均勻對稱布置。另外,還應注意頭道梁拱腳附近截面的尺寸擬定,克服地震內力造成的大偏心受壓狀態給結構配筋設計增加的困難。 2 、橫槽向抗震性能分析1 )可利用調整構件質量的方法,使得結構的某些構件的地震荷載分佈均勻一些。On the contents of two sides abovementined, this paper attempts to do some initial researches from three angles as follows : 1, the analyses of anti - seismic features on longitudinal direction of the aqueduct l ) the seismic longitudinal effects are small. the vibrant characters are decided from the structure integration and rigidness of piers and main arch - ring of the aqueduct, so the following measures should be taken in order to weaken and isolate seismic influence : properly broadening the section sizes and adopting the high class concrete, lowering the height and barycenter of building, setting hoop steel bars so as to increase the plasticity of the concrete which can absorb the seismic energy and prevent the damages due to stress centralization on the linkages and changing place
本文試圖就上述的這兩大方面的內容,從以下三個角度進行了初步研究: 1 、縱槽向抗震性能分析1 )湯峪河吊桿拱支承結構的縱槽向地震效應較小;吊桿式拱架結構動力特性取決于槽墩和主拱圈的剛度,以及結構的整體性,故適當加大構件截面尺寸或提高砼標號,盡量降低結構的建築高度和重心,在構件連接和變截面處增設梗脅,按照約束混凝土的要求來加強箍筋的配置,增加砼的延性,以克服地震時構件連接和變截面處的應力集中造成的坡壞,並吸收大量的地震能量,從而起到隔震,減震的效果。Finally, the thesis primarily sets up the internal force model of the supporting structure system in the bi - arch tunnel, namely, the distribution model of the surrounding rock ' s pressure, the internal force model of the steel framework and the axial force model of the anchor bolt, and these results can have the guiding significance to the design and construction of the similar tunnel engineering
最後,結合有限元的理論計算及現場實測數據的分析,初步建立了雙連拱隧道支護結構體系的內力模型,即:圍巖土壓力模型、初期支護鋼拱架內力(主要為軸力和彎矩)模型以及錨桿軸力模型。充分理解和闡述了構件的工作狀態,對今後類似隧道工程的設計和施工具有一定的指導意義。The truss arch structure is a three - dimensional higher statically indeterminate structure, and no definite expression of the performance function can be given for its unbelievable complexity
桁架拱結構是一個高次超靜定的復雜三維結構,構件的功能函數沒有明確表達式。Based on the study for the methods of structural reliability analysis, including monte carlo method, response surface method and stochastic finite element method, response surface method ( rsm ) is selected. based on the random analysis of aqueduct ' s frequent actions and resistances, by rsm method together with the fem method and form method, the reliabilities of its primary poles can be analyzed and the reliability of the structure be reached
利用此方法,在對渡槽常遇荷載的不確定性分析和抗力不確定性分析的基礎上,結合結構分析的確定性有限元法( fem )及可靠度計算的一次二階矩法( form ) ,對桁架拱結構主要受力狀態構件進行了可靠度分析,從而對結構的可靠性進行了評價。The conclusions are list as follows : ( 1 ) the mechanical properties of different parts of the bridge are as follows : arch is under the combined action of compression and bend ; open spandrel beam is under the combined action of tension and bend ; close spandrel beam is under the combined action of compression ( or tension ) and bend, but the axis force is small
本文得出的結論如下: ( 1 )空腹式剛架拱橋的受力兼具梁和拱的特點。結構各部位的受力特性如下:斜腿為壓彎作用;空腹段梁體為拉彎作用;中跨實腹段梁體為壓彎作用或拉彎作用,但軸向力較小,受力更接近純彎構件。According to the bearing load institute of mainly bearing component, the basic form of bridge can be classified into beam bridge, arch bridge, rigid frame bridge, suspension bridge and assembly system bridge etc. also according to the location of trip lane, it can be classified into top travel bridge, middle travel bridge and lower travel bridge
