Seismic Optimization of High Cantilever Multianchor Pile Strengthening Soil Slopes against Earthquakes

Figure 4

Shaking table test model design drawing (unit: cm). (a, b) The profile diagram of the optimized multianchor cable antislide pile and the unoptimized multianchor cable antislide pile. (c) The top view of the vibration platform side slope model. For the optimized multianchor pile, the pile is prefabricated in advance, and a layer of EPS foam is pasted on the side of the pile mound. The height × width × thickness of the EPS foam is 109 cm × 4 cm × 2 cm, as shown in the dark blue part of Figure 4(a). In addition, an energy-dissipating spring self-coordinating device is set between the anchor head and pile. Screws and gaskets are used to simulate anchors to lock the anchor, and the prestress is applied by adjusting the screws. It uses screws and washers to simulate anchors for anchoring and adjusts screws to apply prestress.
