本文首先對國內外的研究現狀作了回顧和總結，然後主要針對土工織物加筋粉煤灰復合體的本構關系和計算理論進行研究，主要內容有： （ 1 ）將土工織物和周圍土體視為一種近似的彈性非線性橫觀各向同性體，研究它的應力應變關系，充分考慮它的各向異性，得到土工織物加筋粉煤灰復合體的本構模型，然後通過大量室內試驗進行分析驗證； （ 2 ）引入有關滲流理論，即柯茲尼-卡爾曼（ kozeny - carman ）經驗公式，將滲透系數引進到土體本構關系中。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。Specification for pozzolanic pulverized - fuel ash cement
