Abstract

From investigations of damaged earth structures after earthquakes, anchored sheet pile wall has proved to be an excellent seismic structure. However, due to the complexity of the stress system, some fundamental theoretical issues have not been completely solved, so the theoretical development of the structure lags behind application, especially in the development of seismic design theory. In order to make up for this deficiency, a new simplified approach was proposed in this paper, based on previous research. In this approach, the dynamic coupling effect of the pile–soil–anchor was considered, and governing equations were established. In addition, to verify the applicability of the proposed approach, large-scale shaking table tests were performed. In the tests, similitude ratios and similar materials were appropriately applied, and horizontal and vertical acceleration time histories recorded at the Wolong station in the Wenchuan earthquake, China, were used to excite the model. Many time history curves, including dynamic and total earth pressures acting on the stabilizing pile, the cable tensions and the displacements of the wall were obtained. By comparison of the earth pressures and cable tensions between the calculations and tests, the correlation coefficient is 0,943 and 0,890 for earth pressures and cable tensions, respectively. It illustrates that the correlation coefficient between tested values and theoretical results using the proposed theoretical calculation approach is high and close to 1,0, and it is proved that the proposed approach is suitable for practical application.
