Abstract

The invention discloses a floating pile longitudinal vibration analysis method based on layered saturated virtual soil pile. The virtual soil pile under the solid pile is introduced, and by assuming that the virtual soil pile, the solid piles, and the characteristics of the surrounding soil and the subsoil around them, the saturated virtual soil pile model is adopted, thereby considering the saturation characteristics of the soil around the pile and at the bottom of the pile, and being able to reasonably consider the influence of the thickness of pile foundation soil and other factors on the longitudinal vibration characteristics of pile foundation. The method can be used to study the longitudinal vibration characteristics of floating piles in saturated soils. The three-dimensional saturated soil model can consider the three-dimensional wave effect around piles and the soil under piles, and the longitudinal stratification can consider the stratification characteristics formed by the natural sedimentation of soil, which can provide theoretical guidance and reference for the dynamic testing of piles.

Description

technical field [0001] The invention relates to the field of construction, and more specifically, to a method for analyzing the longitudinal vibration of floating piles based on layered saturated virtual soil piles. Background technique [0002] According to the relationship between the pile and the bedrock, when the bottom of the pile does not reach the bedrock, that is, when the pile floats in the soil around the pile, it is called a floating pile. The bottom of the floating pile can be regarded as elastically fixed, and under the action of static load or dynamic load, the bottom of the floating pile can produce axial displacement. [0003] At present, in the case of floating piles, most of the existing studies have simplified the soil at the bottom of the pile to the Winkler model, and the spring and damper coefficients are usually selected according to experience, which cannot reasonably consider the influence of the fluctuation effect of the soil at the bottom of the pi...
