In view of bearing capacity of the elastoplastic theory analysis, the author made a comparison between the achieved bearing capacity limit load pi / 4 of round base ( space problem ) and the limit load pi / 4 of bar groundwork foundation design ( plane problem ) from soil mechanics at home and abroad as well as foundation criterion, and explained why the value of formula in present design criterion from soil mechanics is inclined to be conservative. in the light of the author ' s many years experience of vibration test on the spot and the research work of relevant projects, the author worked over the dynamic pile testing of the bearing capacity of foundation and batholith, and gathered the parameter of dynamic analysis and testing. the author also talked over the difficult point of pile foundation design criteria in present batholith engineering world, i. e. the confirmation of batholith bearing capacity of pile end, from the following aspects : a ) confirmation of single axis counter - pressure strength of rock in house ; b ) f. e. m calculation of elastoplastic model ; c ) calculation of soil mechanics ; d ) deep well load test

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
本文僅就嘉定電廠二期工程中的三根試驗樁的靜載試驗進行了分析和研究，利用樁土體系荷載傳遞分析計算的基本微分方程及應力-應變轉換原理，結合預埋電測元件的樁身率定，對三組不同種類、不同施工工藝、不同持力層中的樁的豎直、水平承載特性進行了分析、比較和歸納，通過大量、全面的實測數據，經過整理、轉換和推演，揭示了不同試驗樁在豎直、水平荷載作用下的應力變化規律和樁身變位、撓曲變化規律，最終提供試驗場地土層和樁的承載特性，為該工程合理設計樁型提供了可靠的設計參數，為確定科學的施工工藝提供了有力的依據。 -
It was shown that the position of neutral point of pile shaft varied with the consolidation of surrounding soil and the magnitude of pile - head load
利用該模型分析了大面積堆載下，在樁頂作用大小不同的豎向荷載以及樁側土達到不同固結度時再施加樁頂荷載情況下，樁身摩阻力的發展變化規律。 -
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
同時，對粉性土的土抗力特徵及其影響粉類土層中樁的荷載傳遞性狀的有關因素，以及對進行過高應變測試后又進行了低應變完整性檢測的斷樁進行了淺顯的分析，疏誤之處，敬請指正。
