摘要：

Using the strain hardening elastoplastic constitutive model which is suitable for numerical analysis of deep excavations in close proximity to sensitive properties, the effect of the anchor on deformation and force of double-row piles is discussed. Increasing the anchorage angles can effectively reduce not only the maximum horizontal displacement of double-row piles but also the bending moments of the back row piles. Increasing the anchorage forces can only effectively reduce the maximum horizontal displacement of double-row piles. The bending moments increase when the anchorage force is larger. In the actual design, we should choose the possible larger angle between anchor and the back row piles and actively control the anchorage forces along with the monitoring.
