rise of arch
解釋
矢高-
I did not now watch the actors ; i no longer waited with interest for the curtain to rise ; my attention was absorbed by the spectators ; my eyes, erewhile fixed on the arch, were now irresistibly attracted to the semicircle of chairs
這時我不去觀看演員了，不再興趣十足地等候幕啟，我的注重力己被觀眾所吸引。我的目光剛才還盯著拱門，此時已不可抗拒地轉向了排成半圓形的椅子。 -
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。 -
In this paper, a 3d finite element analysis software ( fzfx3d ) was compiled to simulate the construction process of mass concrete structures constructed with sequence method. based on the practical project xiluodu arch dam, the dam ' s construction process was simulated by a small time step size, 0. 5 or 1 days. the environmental temperature change, hydration heat rise, artificial cooling, creep, volume deformatio
運用laplace變換方法將溫度的求解表示為只與空間坐標及澆築時間有關的函數，從而避免了用隱式差分法、有限元法求解時需求解聯立方程的因而對測點選擇的依賴，也避免了顯式差分法求解穩定性受時間步長，測點間距大小限制的缺點，因而具有測點布置靈活的特點。 -
That the arched roadway with the ratio of 0. 2 between arch rise and roadway width is substituted fur rectangular roadway can obviously improve the stress state of roadway surrounding rocks, reduce the deformation and the plastic yield area of roadway surrounding rocks, greatly strengthening the stability of roadway surrounding rocks
採用矢跨比為0 . 2的圓弧拱巷道代替矩形巷道，可顯著改善巷道圍巖應力狀況，減小巷道圍巖變形量，減少圍巖塑性屈服區域，加強巷道圍巖的穩定性。
