针对工程中常见的曲线和折线预应力筋布置形式,基于孔道摩擦损失线性化和正反摩擦损失斜率相等的假定推导出具有普遍意义的锚固损失计算公式,可对现行规程公式进行修正.
In view of the common curves in engineering and the arrangement of prestressed tendons in broken lines, based on the assumption of the linearity of the friction loss of the tunnel and the equal slope of the positive and negative friction losses, the calculation formula of the anchorage loss with universal significance can be derived, and the existing procedure formulae can be revised.
