Problems solved by technology

However, the single-phase virtual soil pile model assumes that the soil at the bottom of the pile is a single-phase medium, and does not consider the saturated two-phase medium of the soil at the bottom of the pile, which is not applicable to the longitudinal vibration of the floating pile foundation in saturated soil.

Abstract

The invention discloses a longitudinal vibration analysis method of a floating bearing pile based on a saturated virtual soil pile. The saturated virtual soil pile model is adopted, and the saturation characteristics of the soil around the pile, the soil at the bottom of the pile and the fluctuation effect of the soil at the bottom of the pile can be considered at the same time, and it can be applied to For the longitudinal vibration of floating piles in saturated soil, the three-dimensional saturated soil model can simultaneously consider the three-dimensional fluctuation effects of soil around the pile and the bottom of the pile, which can provide theoretical guidance and reference for dynamic detection of pile foundations.

Description

technical field [0001] The invention relates to a method for analyzing the longitudinal vibration of floating piles, and more specifically, to a method for analyzing the longitudinal vibration of floating piles based on 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 o...
