ANALYSIS OF PILE'S BEHAVIOR UNDER VERTICAL LOAD IN CONSIDERATION OF RELATIVE DISPLACEMENT BETWEEN PILE AND SOIL

摘要

The behavior of pile is analyzed based on elasticity theory and relative displacement between pile and soil is considered. The method is compared with load transfer method and shear displacement method. Interaction between pile and pile can be considered by the method. Continuity of the soil around the pile can be considered into the method. By the method the settlement of the ground around the pile can be calculated. The method isn't simple superposition of load transfer method and shear displacement method. Degradation of the method is consistent with load transfer method and shear displacement method respectively. The interaction coefficient between pile and pile reduces as the pile load increases. The research can offer reference for pile's analysis.
