摘要
对碾压混凝土拱坝中设置诱导缝的工作机理和作用进行了探讨 .实例计算结果表明 :在诱导缝未开裂时 ,其削弱程度对坝体应力的释放程度有很小的差别 ,而对坝体应力分布规律几乎没有影响 ;一旦诱导缝开裂 ,则坝体中的拉应力大为降低 .这说明只有合理地设置诱导缝 ,才能使其发挥释放应力、保护坝体的作用 .
This paper analysizes and discusses the mechanism and effectiveness of crack director of roller compacted concrete arch dam. The results show that the weaken of crack directors has a little influence on stress release and little influence on stress distribution when the crack directors is uncracked. Once it cracked, the tension stress in the arch dam will reduce greatly. This shows that the crack directors must be set reasonablely so that they can play the role of releasing stress and protecting dam.
