Experimental and Theoretical Study for a Displacement-Controlled Design Method of Embedded Cantilever Retaining Walls (Piles)

Displacement control is critical to the design of retaining walls, especially in urban areas, avoid any potential damage adjacent structures during excavations. In this study, model tests are first conducted investigate stress and deformation mechanisms an embedded cantilevered (ECR) wall The development top displacement active passive earth pressures acting on ECR walls excavations studied. Upon experimental observations, a displacement-dependent pressure coefficient proposed derive analytical solution predict both (pile), where value mode (pile) taken into account. Comparisons between predictions test results carried out. A good agreement observed, which shows validity solution. Based solution, displacement-controlled method for (piles) that takes account location rotation point proposed. Parametric studies demonstrate impact excavation depth parameters (piles).
