  1. 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。
  2.

    在鋼管混凝土拱肋斷面上，鋼管對內填混凝土的環箍效應具有非均勻性，在拱軸方向上環箍效應也呈現非均勻性。驗證了材料的橫向變形系數、混凝土標號等參數的變化將引起環箍效應的明顯改變；混凝土的收縮、徐變和膨脹混凝土的應用導致鋼管混凝土的環箍效應發生變化並使截面的應力發生重分佈；並總結了其變化的基本規律。
  3. The expansion agents can only make up the shrinkage to some extent, and the compensation effects would be reduced when the retardener and fly - ash are used. the expansion agents are not panaceas to avoid the shrinkage cracking as expansion can also reduce the concrete soundness. under bad curing condition, the polypropylene fibrillated film fiber can improve concrete ' s anti - crarking property, while the nominal steels have very unobvious effects. to reduce the concrete shrinkage thus avoid the cracking, the former factors must all be taken into account in concrete proportion design to develop sound concrete

    研究結果表明，水泥的品種和用量是影響混凝土收縮值的主要因素之一，當混凝土中水泥用量超過470kg / m ~ 3時，混凝土的收縮值超過400 10 ~ （ - 6 ） ，在約束狀態下存在高開裂風險；採用細砂使混凝土單位用水量顯著提高，收縮值也大幅增加；優質粉煤灰總體上能抑制混凝土的收縮，以超量方式摻入其抑制作用更加明顯，但粉煤灰混凝土早期的粘聚性較差，應注意養護，以免失水產生龜裂；早強減水劑和緩凝減水劑都會使混凝土收縮值增加；膨脹劑只能補償混凝土部分收縮，同時受緩凝劑和粉煤灰的抑制，而且膨脹使混凝土的體積安定性增加了不確定因素，膨脹劑不是解決混凝土收縮裂縫的良方。
