摘　　要：卵形消化池预应力筋张拉时,在上下束环向预应力筋张拉端锚固槽交错角不同布置方式下,通过对每一循环段内预应力筋环向各点预应力损失结果的分析对比,本文提出了环向预应力筋张拉端锚固槽交错角布置的优化方案以及环向预应力损失合理取值的方法。In this article, an optimal scheme of the arrangements of alternate angle of anchorage notches of the stretching ends of circular unbonded tendon and a method of reasonable numerical value selection have been proposed, by analyzing the circular prestressing loss and by comparing the prestressing loss results in every points along the circular unbonded tendons in each cyclical segment under the different arrangements of the alternate angle between stretching ends of the upper and lower circular unbonded tendons in the egg-shaped digester.

关 键 词：卵形消化池 环向预应力筋 循环段 张拉端锚固槽 交错角
