Experimental Research Of The Mechanic Function Of Reinforced Soil-cement Pile

In recent years, the reinforcement soil-cement pile supporting structure which is made of soil-cement and section has been widely used in the world, while the supporting structure made of a new reinforcement soil-cement pile in which the section is replaced with a reinforcement cage has not been applied. The research on reinforcement cage cement pile is still in the stage of indoor, and the entity pile added with reinforcement cage has not been studied.In this paper, Through the entity tests of cement pile to study the forces conditions when the reinforcement cage cement pile used as the supporting structure.Through the experiment, the horizontal displacement on top of the pile and bending moment and other mechanical properties and changes were studied. in the case of excavate, heap load, groundwater level rose, crown beam loses binding and secondary excavation.In the process of excavation, the soil cement pile experienced a complex process of change in stress. The maximum bending moment of the reinforcement cage cement pile occurred at the excavation face. The embedded depth of the reinforcement cage cement pile is preferably 0.9 times of the excavation depth.The horizontal displacement of the reinforcement cage cement pile supporting structure is large, so the excavation depth should not be too deep, and the anchor element should be increasedThe impact of the heaped load for reinforcement cage cement pile is mainly reflected at the impact of the force on the top of the pile at the the initial stages of the heap load.Groundwater level rise not only affected by the forces of the pile, but also changed the intensity of the pile, affect the distribution of bending moment.In the case of the pile crown beam loses constraints, the bending moment changed dramatically, the bending moment of the pile above the changed most obvious excavation face.The impacts of secondary excavation on reinforcement cage cement pile supporting structure mainly reflected at the change of the force of the original excavation face and the new surface excavation, the affect on the embedded solid side and crown beam on top of the pile is not obvious.
