Slope Seismic Response with Different Anchoring Conditions

A three-dimensional model of slope was established by the Finite Element software and analyzed through numerical analysis method, thus to find the regularity and characteristics of seismic response of the slope under different anchoring conditions. Displacement and acceleration response was analyzed through the monitoring points on the side slope and the result was compared with the case without support. Meanwhile, the response regularity and stress characteristics of the anchors were analyzed for the three support methods. It is concluded that support structure can effectively limit the slope deformation and inhibit PGA amplification factor of the slope. Under the action of earthquake the stress of slide-resistant pile and axial force of the anchor increase with diachronic earthquake constantly, and become stable finally. There is a certain reference value for the conclusion of the study on seismic design of composite anchored slope and prestressed anchor anti-slide pile supporting slope.
