| Popis: | Anchored stabilizing pile is a typical earthquake-resistant structure in reinforced slope with advantages of safety, reliability and low cost. It demonstrated excellent seismic performance during the 2008 Great Wenchuan earthquake. However, due to the complexity of the structural system, the coupling relationship between soil, pile, and anchor cable is not well understood at present. This paper developed an analytical model in modeling the dynamic responses of the pile, anchor cable and soil slope system based on Winkler elastic foundation beam theory. The seismic design of the anchored sheet pile wall can then be carried out. An experimental shake-table test was conducted to validate the proposed analytical model. Through the test, the displacements of the pile, axial force of the anchor cable, and earth pressure along the pile derived from the analytical model were validated by the test results. It shows that the proposed analytical model is suitable for the practical application and can provide theoretical basis for dynamic response analysis and seismic design of anchored sheet pile wall. |
