摘要
通过4根预应力砼靠船桩的试验,并结合有限元分析计算,研究了张拉控制应力、砼强度、配筋率等对靠船桩的裂缝形态、裂缝的闭合性能、桩的极限承载能力、总的变形性能和吸能效果的影响。在试验和理论分析计算的基础上,对预应力砼靠船桩的张拉控制应力、砼强度、截面配筋等提出了设计建议。
By testing on the characteristics of four prestressed concrete berthing - piles and doing theoretical calculations. This paper discussed the influence caused by parameters such as initial tensile stress., strength of concrete and ratio of reinforcing bar. Based on the results, some suggestions for practical design are given.
