In urban areas with scarce land resources, many deep excavations are performed adjacent to flexible retaining walls. This study investigated the influence of a flexible retaining wall on the performance of an adjacent deep excavation through numerical modeling. The numerical method incorporating the hardening soil small-strain model and input parameters were primarily validated using a well-documented case. Hypothetical models with different spacings between the deep excavation and existing flexible retaining wall were established to study the deformation behavior of diaphragm walls and characteristics of lateral earth pressure. Parametric studies were carried out to investigated the influence of the excavation width, wall depth, and bending rigidity of retaining walls on the performance of the excavation. Finally, the mechanisms of the flexible retaining wall to influence the mobilization of the arching effect in confined soil were discussed. Results show that the adjacent flexible retaining wall aggravates maximum wall deformation and leads to the inclination of the excavation. The impact is mainly attributed to the redistribution of lateral earth pressure resulted from the mobilization of the arching effect. However, the influence of the flexible retaining wall on the magnitude of the resultant force of lateral earth pressure is insignificant. Both qualitative analysis and numerical results prove that the general shape of the major principal stress trace is a curve convex to stabilized soil when the arching effect is generated.
