恆直公式-
The calculation modes of the coefficient of shrinkage and creep of the bulgy core concrete in steel tube are discussed. based on a few reasonable hypotheses and the stress - strain relation of concrete acquired by the " adjusting valid modulus depending on load time " method, a compact formula is reasoned out, which is applied to calculate the equivalent elastic modulus of the bulgy core concrete considering the affection of shrinkage and creep. so, the analysis of the affection on cfst arch bridge by shrinkage and creep can be progressed by pole - girder fem, further more, the analysis precision is quite high
本文還對核心膨脹混凝土特殊的收縮、徐變系數計算模式展開了探討，在合理的假設前提下，採用「齡期調整的有效模量法」得到的混凝土的本構關系，推導出鋼管內核心混凝土在考慮徐變影響后的等效彈性模量計算公式，並以此為基礎採用桿系有限元方法來對鋼管混凝土拱橋進行較高精度的收縮徐變分析。 -
Finally, the three kind of calculating formula about ultimate bearing capability under the sticking gfrp to reinforce concrete pole will be brought forward according to experiments " result, which is valid can be used in many other practical reinforce projects effectively
最後提出gfrp組合rc柱設計承載能力的三種不同計算公式即箍筋比擬法、綜合系數法、近似平衡法，以便能有效地應用到實際加固工程中去。通過本試驗中的試驗數據證明，這三種方法都是有效的。 -
Partially prestressed concrete structure has been widely used in the field of civil engineering. the deformation is very important for prestressed concrete members, for they are thinner than those of reinforced concret owe to the adoption of hign - intension material and developed technic of design and construction. at present, there are some formulae for deformation in the criterion of many countries. mostly there are 3 methods in use : double linearity method, method of valid inertia and curvature integral calculus method. this article will discuss the influence of material, spa, construction form, and adjust the formula for stiffness of gb50010 - 2002 to a new uniform formula for deformation
在土木工程領域，部分預應力混凝土結構因其良好的跨越能力和經濟性而得到了廣泛的應用，並發揮了巨大的作用。由於採用了高強度材料並進一步改善了設計和施工技術，預應力混凝土構件一般比普通鋼筋混凝土構件更為細巧，因此，撓曲變形問題顯得尤為重要起來。目前，各國規范對于部分預應力混凝土構件的變形計算均有相應的公式，變形計算的關鍵是剛度的計算。 -
It is true that the all formula from conformal mapping is valid only for tem modes
嚴格地說，採用保角變換理論導出的所有公式只適用於tem波。 -
Based on the idea of the measured displacement can be divided into elastic and plastic parts, elastic parameters can back analyzed by the elastic displacement, which is the measured instant after blasting excavation. the strength parameter can be got by plastic deformation, which is the measured during the period of construction loop without blasting excavation. lastly, depending on fenner formula, a new and valid evaluating criterion for tunnel stability is presented and the effect of deformation modulus, cohesion, internal friction angle and overburden can be considered
以解析理論為基礎提出一種實用而簡便的圓形洞室彈性反分析方法，且將其應用推廣到其它洞型、分步位移等不同情況；提出一種圍巖強度參數反演方法，並對其可靠性進行了初步研究； （ 4 ）依據芬納公式提出了能夠考慮圍巖變形模量、強度參數、埋深等主要因素的、新的、有效的圍巖穩定性評判方法。 -
This formula is no less valid in regard to the relation between individuals and the groups to which they are socially tied or, if these groups are subsumed under the over - all concept or feeling of sociation, in regard to the relation among individuals in general
這公式也適用於被社會結合的個人之間以及團體之間的關系，如果這些團體被歸入社會化的感覺會概念中的話，也適用於一般個人間的關系。
