As the study was performed successfully in the previous stage concerning the fold strength, the flexural fatigue behavior was to be examined for this concrete
本研究的前期成果已圓滿結束，本文主要是針對這種混凝土的彎曲疲勞性能進行研究。 -
Specimens ’ cracking load under dead - load, fatigue failure characteristic, fatigue life, deflection of span - centre, fatigue flexural rigidity, maximal crack width, development of cracks and strain of concrete and steel bars have been investigated. the influence of fatigue cycle characteristic, ratio of reinforcement, kinds of aggregate and concrete compressive strength on the specimens ’ fatigue behavior has been also investigated
對試件的靜載下開裂荷載、疲勞破壞特徵、疲勞壽命、疲勞荷載作用下的跨中撓度、截面疲勞抗彎剛度、裂縫開展情況及最大裂縫寬度、鋼筋及混凝土在循環荷載作用下應變等內容進行了研究，分析了疲勞循環特徵值、縱筋配筋率、骨料種類、混凝土抗壓強度等因素對試件疲勞性能的影響。 -
The essay researched the compressive strength, bending strength, impact resistance and abrasion resistance of high strength polypropylene fibermesh concrete the mechanism of enhancing the properties of high strengh poloypropylence fibemesh road concrete composite was discussed and analyzed the regression on tensile strengh with portland cement mixed with fiber was derived using experiment the tensile strength of fiber soil stablization with porland cement was increased with dosage and length of fiber while the former was more effective than the latter test and analysis results indicate that polypropylene fiber can not only reinforce the strength of concrete, but also obviously promote the flexural fatigue life by the great stress the application of polypropylence fiber reinforced concrete in pavement construcion are also introduced
文章研究了不同摻量有機纖維混凝土的抗壓、抗折強度、抗沖及性能、疲勞性能及耐磨性等各種路用性能，綜合論述了有機纖維對水泥混凝土路用性能的影響。通過試驗闡述了纖維水泥混凝土各種路用性能與纖維摻量、長度間的關系。分析表明纖維水泥混凝土隨著纖維摻量和長度增加而增加，且纖維摻量對纖維混凝土抗拉強度的影響比纖維長度的影響更大。 -
By far the primary methods to improve the quality of cement concrete is to vary the ratio of differete conpound, but of effection is not evidently the tensile strength and toughness of soil stabilization with portland cement mixed fiber obtained is higher than those of the soil stabilization with portland cenment. adding polypropylene to cement concrete can increase the conrete pavement performance, improve the flexural fatigue property
目前，提高水泥路面使用品質的途徑之一就是通過改善水泥混凝土的配合比來提高水泥混凝土的各種路用性能，但是其實際使用效果並不是很顯著。採用在水泥混凝土中摻加纖維的方法可以獲得比普通水泥混凝土抗拉強度和韌性更高的纖維混凝土。從而大幅度的提高混凝土的彎曲疲勞等路用性能。
