A Mechanism Analysis of Pile-soil Interaction of Micro-pile in Building Heightening and Transformation Sujuan Zhang Civil Engineering School, Shandong Jiao Tong University, Jinan, Shandong, 250023, China Zhangsujuan2007@sina.com Keywords: micro-pile Interaction pile foundation constructed in reverse order heightening and transformation load ratio Abstract：Based upon the characteristics of micro-pile in building heightening and transformation (mainly including the mechanism of the press injection increasing the bearing capacity , the rigid connection between micro-pile and its original foundation), through the analysis of its load characteristics in building heightening and transformation, using the theory of pile foundation constructed in reverse order, then the mechanical mechanism of micro-pile and original foundation is studied and the analysis method of soil-pile-foundation (cap) interaction by considering pile tip penetration displacement and soil compression between pile
In a variety of civil engineering, such as house renovation, overbuilding story, strengthening and rectification of ancient buildings, levees reinforcement, reinforcement of construction against shock, new building foundation, treatment of dilapidated buildings foundation, uneven settlement, processing of underground cavern collapse, slides treatment, embankment reinforcement, pit supporting, foundation excavation and retaining, micro-pile is widely used.
Calculations of micro-pile bearing capacity In the traditional pile foundation design, the pile bears all the load of superstructure, the pile cap or raft does not. but consulting practical engineering data both at home and abroad, we will find that pile cap or raft bears the load of superstructure, for example, Hyde Park, UK, its pile cap bears 40% of the load, furthermore, there is example showing that pile cap can bear the load as far as 60%, therefore, traditional pile foundation method does not take the effect of pile cap or raft into account, which is not practical.
