This paper deals with seismic response of a tunnel - soil system immersed tunnel , as an underground structure , must be compatible with the deformation of the surrounding soil thus the simplified model for a tunnel - soil system is established through two steps at the first step , an mdof system is developed for modeling the foundation soil to this end , dynamic behavior of the foundation soil is analyzed a typical section of the foundation soil simplified as a single mass - spring system on the basis of some equivalent criteria those mass are linked longitudinally by elastic springs to form an mdof system at the second step , the tunnel is treated as a beam on elastic foundation ; that is , the tunnel is connected with the soil massed to form a tunnel - soil system this model has been applied to the seismic analysis of huangsha fangcun immersed tunnel across the pearl river in guangzhou design recommendation is proposed on the basis of this analysis
研究沉管隧道在地震條件下整體受力的分析方法分兩步建立計算模型第一步通過分析場地地基土切片的動力特性,根據等效原則將其化為等效單質點體系,然後在縱向用等效彈簧連接而成為多質點體系的地基土計算模型;第二步將隧道看作彈性地基梁與上述多質點體系通過等效彈簧連結而得到土隧道體系的計算模型本文結合廣州黃沙芳村珠江水下隧道工程實例建立了具體的計算模型並對多種不同的約束條件,進行了縱向與橫向地震響應時程分析,為該隧道的抗震設計提供依據In allusion to section modality and transverse joint of common span bridges, we choose two kinds of calculating theories in transverse distributing calculate process : the theory of rigidity crossbeam and the theory of hinged girder and slab. making the use of the theory of optimized design, i constitute mathematics model and choose appropriate calculated method. and find the form and detail dimension of section when beams of the bridge satisfy bending moment ^ shearing force and torsional moment
在用橫向分佈理論計算單梁扭矩過程中,針對現有常用跨徑橋梁的截面形式和橫向連接狀況,選取了兩種計算理論:剛性橫梁法和鉸接梁(板)法,利用結構優化設計原理,建立主梁承載力的數學模型,選擇合適的優化計算方法,得出在滿足彎剪扭承載力要求時主梁的細部尺寸。After comparing between the finite - element analysis and experimental results, the author verified the fem. then according to the chinese code, the nonlinear finite model of the beam - to - column is established which are made of different size components. the responses of beam - to - column web moment connections which are made of different size components are compared and analyzed from three facets, and the conclusions about the joints behavior are drawn : thicken the connection plate, lengthen the connection plate or use a back - up stiffer can improve the connection behavior, consist of improving the behavior of load - supported and reducing the stress convergence in the flange moment plates
本文根據我國規范的有關規定,自行建立了12個不同構件尺寸的樑柱腹板連接的三維有限元模型,對不同構件尺寸的樑柱腹板剛性連接節點在單向荷載作用下的反應進行了研究,從結構的mises應力等值線示意圖、梁端加載處的荷載? ?位移曲線、翼緣連接板兩端的mises等效應力以及翼緣連接板與柱相連接的三邊的mises應力等值線示意圖四方面進行了比較與分析,從而得出了不同構件尺寸的樑柱腹板剛性連接的在受力行為上的結論:增加翼緣連接板的厚度、增加翼緣連接板的長度以及採用柱的橫向加勁肋均可以改善節點的受力性能:提高節點的承載能力;減小翼緣連接板內部與柱翼緣邊的的應力不均勻現象,從而避免試件過早地發生破壞。In chapter 2, proposes an analytical model to the grillage girder, and then establishes its equations by force method. for the primary structure, the upper longitudinal beam is regarded as the finite length continuous girder by elastic point supporting, and the lower cross girder is regarded as the finite length beam on elastic foundation. a computing program is made by qbasic language
第二章主要提出了彈性支承交叉梁系模型,用力法建立了結構靜力求解方程,基本結構的處理上,上層縱梁視為有限長點支承連續梁,下層橫梁視為有限長彈性地基梁,用qbasic語言編制了求解程序。The tower shafts, most of which are hollow and varying in cross section, and altitudinal construction bring trouble to the form work and the stress of strand wire. and the cracks on the crossbeams will be caused by the following - deformation of the bracing structure joints, elastic deformation , uneven settlement and temperature changes. the additional stress of the base slab and the foundation is caused by the deviation of cable bent tower construction
但大跨度橋梁混凝土索塔施工設備進場及現場管理都比較困難;塔柱多為空心變截面,且為高空作業,給模板工程及預應力張拉帶來一定困難;支撐系統連接的間隙變形、彈性變形、不均勻沉降以及環境溫差可導致橫梁裂縫;索塔施工偏位會引起的承臺和基礎的附加應力,對加勁梁的架設影響大;懸吊結構未完體系(架設時)施工階段的風致振動往往影響到施工的安全和質量;實心塔柱部分體積較大,易產生溫度裂縫。分享友人
