Experimental Study On The Reinforced Mixing Pile Respectively Subjected To A Vertical Load Or A Lateral Load

Based on the analysis of the pile constituded by single material and experimental study on three groups of engineering test pile, the thesis finds the features of the load bearing capacity and displacement of the piles of this kind, which are respectively subjected to a vertical load or a lateral load, and the practical applying of high-accurate data collector, technique of waterproof insulation and testing technique of burying in the body of piles are introduced also. The vertical and lateral loading features of the three groups of piles are analyzed, compared and summed up with basic integro-differential equations calculating the pile earth system's load transmit, transforming principle of stress deforming and pile body rating of burying electric measuring element. The loading features of soil layer and pile at testing spot, reliable design data for pile type and base for scientific construction technique are provided, too. I also do some exploration to the resisting features of powdery earth and the factors affecting the load transforming of pile in the powdery earth layer through this big test.To sum up, according to the test, it finds that this pile has not only high vertical load bearing capacity but also high lateral load bearing capacity, and it is economical and fit for the tier buildings and tall buildings which are founded on the deep soft subgrade foundation soils.
