A New Prestress Loss Calculation Model of Anchor Cable in Pile–Anchor Structure

Pile–anchor structures are widely used in foundation excavation and slope reinforcement due to their safety reliability. However, the pile–anchor have common problem of prestress loss anchor cables, which may reduce stability structures. To accurately predict a new calculation model was established, availability verified through engineering cases. Meanwhile, aiming at long-term coupled creep behavior cable–rock soil studied an suitable for is proposed. The test confirms that could describe cable rock mass. models provide theoretical basis study cables structures, guiding significance design construction engineering.
