Abstract: The performance of the anchored soldier pile supporting system in the deep excavation is numerically investigated by using a commercial software PLAXIS. The analyzed stress in the anchor as well as the horizontal deflection in the soldier pile wall are compared with the observed data. The result indicate that, both the stress in the ground anchor and the horizontal deflection in the soldier pile are acceptable. The anchored soldier pile system can be used in the large deep excavation project. The observed stress and the deflection are consistent with the analytical results.
