Pile-soil Load Transfer Mechanism In The Static Load Test And Research

The static loading test for three group of testing piles of jiading power plant secend stage project are analyzed and studied in this thesis, and the practical applying of high-accurate data collector, technique of waterproof insulation and testing technique of burying in the body of pile are introduced also. The vertical and horizontal loading features of three group of piles of different kind and constructing technique in different earth layer at the pile point are analyzed and compared and summed up with basic integro-differential equation calculating the pile earth system load transmit , transforming principle of stress-deforming and pile body rating of burying electric measuring element. Changing law of stress, and changing law of pile body shifting and bending for different testing piles under vertical and horizontal load are showed so that 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. 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. Please point out my mistakes in this thesis.
