在经典摩阻理论计算公式的基础上,建立了锚固时考虑反向摩阻的力筋应力损失计算公式,物理概念明确,且适用于任意形状力筋和单、双端张拉的情形,为考虑反摩阻影响的锚固损失计算提供了可靠的理论依据。探讨了公式的适用范围,对减小锚固损失提出了相应的补偿措施。 Based on the calculation formula of the classic friction resistance theory, the formula for calculating the stress loss of the tendons considering the reverse friction resistance during anchorage is established. The physical concept is clear, and it is applicable to the case of arbitrary shape of tendons and single and double ends tension. The calculation of the anchor loss considering the influence of anti-friction provides a reliable theoretical basis. The scope of application of the formula is discussed, and corresponding compensation measures are proposed for reducing the anchorage loss.
