摘要
腹板斜裂缝产生的主要原因在于竖向预应力的损失,在研究应力损失的原因的基础上,结合实际的施工及设计情况,对如何避免腹板斜裂缝提出建议。
The main cause of the developing of the skew crack is the vertical stress' loss. Based on researching the causes of the stress loss and according to the construc- tion and designing, some measures are suggested to avoid the appearing of the skew cracks.
