Abstract
By using the large physical test to analyze the mechanical effects of the anti-sliding pile towards the slope, this research can analyze the displacement of the top, cut export and the moment. Besides, the changeable rule about the change of the load and the soil pressure and the destruction of slope can be observed and analyzed. The results show that, during the process, the back of the pile top began to separate with the sliding body. Behind the pile, the anchoring section where near the sliding surface also separated with the sliding bed, generating a pumping area. Loading up to the 420kN, the horizontal displacement began to increase rapidly, and when load was 480kN, the horizontal displacement in the cut export also began to grow quickly. The bending moment of the pile distributed in apparent anti-S. The maximum moment of the anti-sliding section is in the place 48cm above the sliding surface. The maximum moment of anchoring section is located under the surface about 22cm deep. The maximum moment of the anti-sliding section is bigger than the value of the anchoring. Furthermore, both the back of the anti-sliding section and the front side of anchoring section are carrying loads in tension. The maximum soil pressure in front of the anti-sliding pile is located in 70cm above the sliding surface. The maximum soil pressure of the anchoring section is near the surface, but this value is zero in the bottom of the pile. In the back of the anti-sliding pile, the maximum soil pressure is in the 40cm above the surface. The soil pressure is bigger in the anchoring section, and the value in the surface is zero. The rule of distribution of the soil pressure apparently opposites with the rule in the back of the pile. The results can provide the design and calculation of the anti-sliding single steel pile some references.
