On the mrp, the truss arch aqueduct is comprehensively researched in this paper, including its structural characteristic, structural calculation and reliability analysis
本文結合南水北調中線工程，對下承式空腹桁架拱排水渡槽的特點、結構計算以及結構的可靠性進行了較全面研究。( 2 ) the common used arch axes are circular arcru parabola arch, catenary arch
（ 2 ）空腹式剛架拱橋的拱軸線一般可取圓弧線、拋物線或懸鏈線。Through the finite element method, this paper compares some variable parameters such as the arch axis, the rise - span ratio and the ratio of spans, which influence the mechanical performances of open spandrel rigid - framed arch bridge. then it summarizes the mechanical properties of this bridge type and the optimal range of these parameters. the plexiglass model test validates the correctness of the finite element method used in this paper. the study will provide reference for the design of this new bridge type
本文採用有限元方法對影響空腹式剛架拱橋受力性能的主要參數：拱軸線型、矢跨比及跨徑比進行了比較分析，總結了這種橋型的結構受力特點以及拱軸線型等參數的合理范圍，為這種新橋型的工程設計提供參考，並通過有機玻璃模型試驗驗證了有限元分析的正確性。Circular arch is rational for big rise - span ratio, but each has his strong point for small rise - span ratio. ( 3 ) the common used rise - span ratios are 1 / 6 - 1 / 12. by the decrease of rise - span ratio, the internal forces are increasing linearly except of the moment of open spandrel beam
（ 3 ）空腹式剛架拱橋的矢跨比一般為1 6 1 12 ，隨著矢跨比的減小，除了空腹段加勁梁的彎矩值線性減小外，其餘截面的內力值均為線性增大。分享友人
