| 摘 要： | 分析了岩土锚索预应力损失的主要因素，建立了锚索预应力损失随时间变化模型，在此基础上，较精确地推算了锚索预应力损失情况及最终损失量，并为锚索预应力计算提供理论依据。通过对襄-十高速公路锚索预应力模拟计算，较好地印证了锚索预应力损失模型的合理性。

| Abstract: | A new method is presented to predict the prestress loss and the final prestress loss of the prestressed anchor cable; based on the study, some conclusions are obtained; and a theoretical basis for analyzing prestressed anchor cable is provided. Simulating calculation of prestressed cables for Xiang-Shi Expressway proves that the method is suitable well for the practice. |
